To start working with a material, to begin with it is necessary to get acquainted with all its properties. This is necessary for that, to know what mechanical effect can be exerted on the material, and also in what conditions and what tools it is possible to carry out its processing.
Brass - metal, so very often its processing is carried out by means of melting. The melting point of brass is a very important characteristic, which must be known, if heat treatment is required.
brass alloy
Brass is a component metal. This means, that most often brass is in alloys with other metals. that most often brass is in alloys with other metals. that most often brass is in alloys with other metals: manganese, iron, that most often brass is in alloys with other metals.
that most often brass is in alloys with other metals, that most often brass is in alloys with other metals, that most often brass is in alloys with other metals: that most often brass is in alloys with other metals, that most often brass is in alloys with other metals.
that most often brass is in alloys with other metals, that most often brass is in alloys with other metals, that most often brass is in alloys with other metals. Awareness of this area can help solve many possible problems.
If you know the melting point of brass, that is, the limit, at which it can be melted, then it will be possible to make various structural elements, possibly at home.
Main characteristics
On such an indicator, how the melting point of brass primarily affects its composition. The temperature in different cases may have different values, ranging from eight hundred and eighty degrees Celsius to nine hundred and fifty.
Of course, it is possible to reduce this range. If there is a need for it, then you should just add more zinc to the alloy. For the opposite effect, do the opposite.
Processing of this metal can be carried out by means of welding, but remember, that in this case it can be demonstrated.
You need to know that important fact, that if you do not take care of coating the surface of this alloy with additional protection, then later will have to face blackening of the surface. It has to do with that, that in contact with air it is slightly oxidized, resulting in a slight blackening.
The surface of brass is quite easy to polish. In order to choose the method of melting for this metal should be, to start, take into account its composition.
Remember, that the brass alloy is very negatively affected by such elements, like lead or bismuth. It has to do with that, that these elements significantly reduce the properties of the material to deformation under conditions, when it is heated.
Brass is a non-ferrous metal, but at the same time it has many special characteristics, inherent only in this material. Metal has some advantages, which directly affect the popularity of the material:
- Brass has high resistance to corrosion.
- The material has a fairly high degree of fluidity, which is a very important factor in its melting.
- It is possible to note also high antifrictional properties of this metal, as well as a fairly low propensity to liquation.
In principle, there are many different advantages, which are attributed to brass, but they are not common, and purposeful. This means, that depending on the brand, the material is used in various industrial fields.
Brass is used in such important areas, both automotive and mechanical engineering. Also from this component metal create a large number of different products for different purposes.
In order to be able to work with such material, you need to first know all its physical properties, which will later provide direct assistance in processing brass at home.
Technical features of brass
- Melting point of brass - 880-950 degrees Celsius.
- The specific heat of this metal - 0,377 kj * kg - 1 * K-1 under thermal exposure to 20 degrees Celsius.
- Material density - 8300-8700 kg / cubic meter.
- Specific electrical resistance (0,07-0,08) * 6-10 Ohm * m.
What to consider when working with brass
The home craftsman uses a lot of products in the home environment, made on the basis of brass.
Many tools are made using brass, it can often be found in various alloys, which can be based on copper or bronze.
If you are aware of that, what melting point is acceptable for brass and its alloys, later it is possible to use this knowledge in the repair or manufacture of various products, which can be used on the farm.
The melting procedure is not without such a universal component ??various subtleties and nuances, which should be known and remembered, to avoid various processing difficulties, as well as the negative consequences of erroneous actions.
Remember, that for all the subtleties of melting brass, certain nuances should be taken into account when melting bronze and copper alloys.
The point is, that these alloys have slightly different melting parameters, which differ from the characteristics of brass, so before, than to start working with such brass alloys, you need to start to learn in detail all their properties. This will prevent annoying errors in their processing, as well as to carry out the work as efficiently and effectively as possible.
To make metal smelting at home, should have certain knowledge and skills, as well as special tools, who will be able to help in the work and take the necessary actions, which involve the melting of brass.
In addition, experienced craftsmen recommend before the procedure of melting brass at home to be patient, because this procedure can not be called an ambulance.
To work, you need to stock up on the following elements:
- technical silver;
- manual gas burner;
- special graphite burner;
- copper alloy.
You need to buy a drill before work, and in sufficient quantities. In addition, to ensure the maximum safe conditions for the surrounding space during the melting of metal, asbestos sheet should be used.
The process of smelting brass is quite time consuming and time consuming, and added strength.
Again, you should take into account the peculiarities of the melting of alloys, containing bronze and copper, since they have slightly different characteristics and properties, which means that when melting will have to use a different temperature of thermal exposure.
The process of melting brass should be proceeded only in that case, when the workplace is properly prepared, and all working tools are in place and ready to work.
The order of works
To begin, prepare a muffle furnace. It will carry out all the main work.
Before you start directly melting, the operation of existing burners should be checked, which will be used in the process. in addition, you should have a special vessel at hand, made of refractory material. This material is a crucible, so it will be possible to apply it.
Previously purchased asbestos sheet, should be laid on the surface of the base. A very important factor is to maintain good ventilation in the room, in which all work will be carried out.
Before melting, brass should be ground, that is, to create a crushed mass. Remember, that the fewer pieces of metal will be obtained, the easier it will melt later.
Then the crucible with crushed brass is placed in a muffle furnace, then the user sets the required temperature value, using a special temperature controller. After turning on the oven, you can watch the whole melting process through a special small window, which is in such furnaces.
Once the metal is completely melted, the user only needs to carefully open the door of the muffle furnace and get out of it a crucible of molten brass.
Of course, you need to do it, using special pliers, for, to protect yourself from possible burns. In molten brass, by the way, is an interesting property, which is, that a thin film is formed on the surface, which will later need to be removed. This procedure can be performed, if you use ordinary steel wire.
After removal, a film was formed from the surface of the molten brass, you just need to pour the metal into the desired shape, which the user must pre-prepare at his workplace.
Melting with a burner
By the way, there are cases, when the user, Unfortunately, cannot use special equipment, designed for melting. In this case, do not despair, because the smelting of brass can be done with gas burners.
The burner must be installed ??in a vertical position and very well fixed. Then on a support establishes a vessel with metal and melting is carried out.
Remember again, that if the brass contains copper in its base, then the temperature will definitely increase, what means, that the metal will melt longer.
