Heat treatment process:

Brass bar has good electrical and thermal conductivity, high corrosion resistance in the atmosphere and fresh water, and has good plasticity, easy to cold and hot pressure processing, easy welding, forging and tin plating, no stress corrosion rupture tendency. Brass is suitable for automatic lathe, CNC lathe processing with ecological environmental protection and health requirements of products, such as electronics, telecommunications, electrical connectors, connectors, hardware, photography, household appliances, drinking water engineering parts. Suitable for bath hot water furnace, liner, crafts, construction materials, chemical industry, electrical terminals.

A kind of metalworking bar, with good machining properties, high electrical conductivity. Mainly divided into brass rod (copper zinc alloy), purple copper rod (higher copper content). Brass bar is an alloy bar made of copper and zinc alloy. It is named for its yellow color. Brass mechanical properties and wear resistance are very good, can be used in the manufacture of precision instruments, ship parts, guns and so on.

Depending on the amount of zinc, there will be different colors, such as 18% to 20% zinc will be red yellow, and 20% to 30% zinc will be brownish yellow. In addition, brass strikes loudly, so it is used to make eastern gongs, cymbals, bells, horns and other Musical Instruments, as well as Western brass instruments are made of brass.

Copper rod belongs to easy cutting brass, there are environmental protection brass rod and ordinary brass rod. Generally, authentic copper bars are made by extrusion process. The copper bars produced by ordinary continuous casting copper bars cannot reach all aspects of performance. The copper bars produced by extrusion process have good tensile strength, high hardness and high straightness. Generally in auto parts, medical parts, electrical parts and other precision copper parts consumption is more. Air conditioning pipe, refrigerator pipe, oil pipe, water supply pipe and mechanical supporting materials, auto synchronous gear ring, Marine pump, valve, structural parts, friction accessories, etc.
