Brass is an alloy of copper with more than 50% Zincum (zinc) is sometimes coupled with Tin (Tin) and Lead (Lead) and Aluminum and Silicon. Analysis of the equilibrium diagram of Copper-Zinc alloy (Copper-Zinc) showed that the alloy of Copper Zinc, Zinc levels above 37% is acceptable in the copper and will form a solid solution called (\u03b1). Copper Zinc in the solution process does not evolve by changes in temperature, thus Brass alloys are not formed by deposition.<\/p>\n

Brass with 37% zinc content above is called “\u03b1 brasses” which is capable of cold working the alloy because of the structure of the solid solution formed. Brass Copper Alloy called \u03b1 brasses is growing by the development of elements in kahirnya will cause distortion of the lattice of copper (“copper lattice”). Phase in which the formation of the red fraction (hot short) brass therefore is not suitable for hot working.<\/p>\n

If the levels of Zinc on Copper alloy exceeds 37% then it happened a second phase of “\u03b2-phase”, located along the \u03b1 phase and the alloy is called “\u03b1 + \u03b2 brasses” with tenacity balanced at room temperature because of the tenacity of replacing the \u03b1 crystalline fragility of crystalline \u03b2.<\/p>\n

Brass of this type have properties capable of heat processing (Hot working brasses), this was due to \u03b2 atom scattering at high temperature ductility and will form the \u03b2 phase and at the same time \u03b1 crystals will become brittle at high temperatures and dissolves into the \u03b2 phase so that the alloy will be resilient to higher Temperaatur.<\/p>\n

Brass with Zinc levels above 45% is composed of crystals thoroughly with properties very fragile at room temperature (room temperature), as seen in the diagram where the balance of Copper-Zinc from Zinc melting point of high alloy lower levels than in Brass with Zinc low, therefore the high alloy Zinc is used as a “Brazing spelter” because of the low melting point, but the connection does not become brittle because during splicing operations Senga levels will fall through the process of evaporation and some will spread into the Brass on the connection.<\/p>\n

The execution begins with the process of heat treatment process called “Stress relief annealing treatment” (see Chapter Heat treatment process), ie the heating temperature to avoid cracking 2500C (Season Cracking), the rift between crystal boundaries that often occurs at the end of each working .<\/p>\n

Some highlights of the Brass types include:<\/strong>
\n1. Cap-Copper; namely Copper dioxide with zinc levels up to 3% have a soft and ductile properties and high conductivity.
\nCap-naming Copper is given in accordance with the usage of the most important functions as a container of Priming Caps on Ammunition.<\/p>\n

2. Gilding-Brass; the type of Brass containing 10% Zinc and through heavy processing that enables not going to happen “season crack” compared with Brass high levels of zinc. Brass is used in the manufacture of pframe “Jewel” and various decorative function.<\/p>\n

3. Catride Brass; This brass has Zinc levels up to 30%, as the name suggests Brass is used as materials for Catride and shell case. The brass has a pretty resilient properties to the type that is capable of Brass cold working and has good tensile strength.<\/p>\n

4. The Standard brasses; although slightly more resilient than Catride brasses, Brass is relatively cheaper because its copper levels were also lower, as well as at lower levels of violence compared with brass like formation necessary for softening to avoid distortion of cold working.<\/p>\n

5. Bases Brass; This brass contains zinc between 36% to 38% with fewer elements dariu \u03b2 phase, are the raw materials products with a relatively cheap price and according to press workmanship, strength is not guaranteed, Brass is commonly referred to as brass or “Common brasses”.<\/p>\n

6. Admiralty brasses; Brass is of the type “Catride brasses” are coupled with elements of tin up to 1% to impart resistance to various forms of corrosion. Brass is used as materials for the condenser and cooling components with water.<\/p>\n

7. Aluminium brasses; The composition consists Brass Brass with 76% Copper, 22% Zinc and 2% aluminum, the use of which is very important as materials for “Marine Condenser tubes” because of its high resistance to corrosion.<\/p>\n

8. Clock Brass and Brass Engraving; Brass or Standard Bases ie brasses were coupled with 1% Lead (lead) capable machine that gives the (machinability) to this kind of Brass. Black tin (lead) does not dissolve in the liquid state in brass, fine particles are left entirely be separated into chips during cutting and lubrication will help the process either during the cutting process and service of lubrication components in the assembly in a difficult position to reach.<\/p>\n

9. Hot-working (\u03b1 + \u03b2) Brass; included in this brass group also is “Muntz-metal” added little elements that will add to the tensile strength of the Brass.<\/p>\n

10. Muntz-metal; Muntz metal is referred to as the “Yellow Metal” (Yellow metals) formed by cold working with the principle of alignment is used as a hot plate diroll or in the form of bars, followed by forging (Forging) or extrusion. Muntz metal is used as an ingredient for the formation of the casting alloys or as an ingredient in steel casting.<\/p>\n

11. Leaded 60: 40 Brass; Turning also called Brass, Brass is an element of the lead at 0.5% to 3.5% on-metal Munzt able to provide properties machine (Machinability) and elemental lead in Brass does not reduce its strength although ductility will decrease and the value of impactnya. Formation with Forging will reduce levels of lead in this Kiningan.<\/p>\n

12. Naval Brass; Muntz metal is supplemented with 1% Tin (Tin) with demikina brass will be very resistant to corrosion and increased strength. This construction is very good with a variety of methods of casting, hot rolling and forging (forging).<\/p>\n

13. Naval Brass; with the content of Lead (lead) 0.5 to 2.0% will also be able to improve the properties of the machine but it would be a little binding in the process of forging (forging)<\/p>\n

14. High Tensile Brass; This brass alloy contains elements hingg 7% consisting of elements of Manganese, Iron,, Nickel, Tin and aluminum are added to Muntz metal with the aim of improving the quality of its mechanical properties, with dmikian will obtain a special type of brass that has a high tensile strength.<\/p>\n","protected":false},"excerpt":{"rendered":"
