[H62 precision brass belt] material

Introduction to the properties of brass supplied by Xinfuhong Brass is an alloy of copper and zinc. The simplest brass is a binary alloy of copper and zinc, called simple brass or ordinary brass. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher its strength and slightly lower plasticity. The zinc content of brass used in industry should not exceed that. Any higher zinc content will cause brittleness and deteriorate the properties of the alloy. In order to improve certain properties of brass, brass that adds other alloying elements to unary brass is called special brass. Commonly used alloying elements include silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass and slightly reduce the plasticity. Brass containing less than aluminum has good processing, casting and other comprehensive properties. The tin added to brass can significantly improve the brass's ability to resist corrosion from seawater and marine atmosphere, so it is called navy brass. Tin can also improve the cutting performance of brass. The main purpose of adding lead to brass is to improve the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance. Adding aluminum to manganese brass can also improve its performance and obtain castings with smooth surfaces. Brass can be divided into two categories: casting and pressure processing products. The product specifications are complete, the price is favorable, the packaging is intact, the copper is pure, the straightness is good, the inventory is large, and the material certificate and report can be provided.
The characteristics and applications of brass are as follows
Ordinary brass is the cheapest, has high strength and hardness and poor plasticity. However, it can still withstand pressure processing well under heat treatment, has average corrosion resistance, and has other properties. and similar. Used for general machine parts, welding parts, hot punching and hot rolling parts.
Ordinary brass has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy to braze and weld, and corrosion resistance, but it is prone to corrosion and cracking. In addition, it is cheap and is a common brass variety that is commonly used. Used for various deep drawing and bending manufactured parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.
National standard brass is suitable for pressure processing in cold conditions and is suitable for welding and brazing. Easy to polish, it is the main alloy for drawing, rolling, bending and other forming. Used for screws, round rollers for pickling, etc.
The performance of national standard brass is between Used for small hardware, daily necessities, small springs, screws, rivets and mechanical parts. National standard brass has extremely good plasticity (the best among brass) and high strength. It has good cutting performance, is easy to weld, and is not resistant to general corrosion, but is prone to cracking. It is the most widely used variety among ordinary brass. Used for complex cold-drawn and deep-drawn parts, such as radiator shells, conduits, bellows, cartridge cases, gaskets, etc.
Neutral brass has extremely good plasticity (the best among brass) and high strength. It has good cutting performance, is easy to weld, and is not resistant to general corrosion, but is prone to cracking. Used for complex cold-drawn and deep-drawn parts, such as radiator housings, ducts, bellows, cartridge cases, gaskets.
Neutral brass has very good mechanical properties, process properties and corrosion resistance. Can be pressure processed well in both hot and cold conditions. In terms of performance and economy, it is somewhere in between. For low load corrosion resistant springs.
High-precision brass has similar properties to brass, but has higher strength and better plasticity. It has higher corrosion resistance in the atmosphere, fresh water and sea water. Used for papermaking mesh, thin-walled pipes, corrugated pipes and house construction supplies.
High-precision brass has high strength, good plasticity, can withstand cold and hot pressure processing, and has excellent welding and corrosion resistance properties. Used for condensation and heat dissipation pipes, siphons, serpentine tubes, cooling equipment parts.
The performance of high-precision brass is similar to that of brass, but its strength is slightly higher. It can be plated with metal and coated with enamel. Used in water and drain pipes, medals, artwork, tank straps and bimetal strips.
High-precision brass has higher strength than copper (but among ordinary brass, it has the lowest thermal conductivity, good electrical conductivity, high corrosion resistance in the atmosphere and water, good plasticity, and is easy to cool , hot pressure processing, easy to weld, forge and tin plating, no tendency of stress corrosion cracking. Used as conduits, condenser tubes, radiator tubes, heat sinks, automobile water tank belts and conductive parts in general machinery manufacturing.
