first, brass plate introduction

brass is an alloy of copper and zinc. the simplest brass is a copper-zinc binary alloy called simple brass or plain brass. brass plate is a widely used lead brass, with good mechanical properties, and good machinability, can withstand hot and cold pressure processing, used in cutting processing and stamping processing of various structural parts, such as gaskets, bushings, etc. the main purpose of brass lead is to improve cutting processability and improve wear resistance, and lead has little effect on the strength of brass.

second, the characteristics of brass plate

1, light weight, good flexibility, easy to construct. 

2. the corrosion resistance is better, which can ensure the waterproof effect of the tunnel in a long time. 

3. compared with pure copper plate and copper iron alloy plate, the tensile strength is increased by 10. 4%, 3% higher hardness. 

third, the difference between copper plate and brass plate

1, the composition is different: copper is very pure, almost pure copper, with outstanding conductivity and plasticity, strength and hardness are slightly weaker and smaller; brass also contains other alloys, low quotation, conductivity and plasticity and copper are slightly weaker and smaller, but have higher strength and hardness. 

2, the function is different: copper content of copper is 99.9%, conductivity, thermal conductivity, resistance, weldability and corrosion resistance is excellent; the density of brass is larger than that of copper, there are impurities, excellent corrosion resistance, conductivity is lower than copper. 

3, the use is different: copper plate is often used in the manufacture of conductive and thermal conductive devices, because it has good corrosion resistance, but also often used in the chemical industry, through cold plastic and thermoplastic processing, can be made into semi-products or products; brass corrosion resistance, often used in elastic components, hardware and decoration materials. 

fourth, the application of brass plate

1. used in general machine parts, weldment parts, hot stamping and hot rolled parts. 

2. used for all kinds of deep extension and bending manufacturing of gifted parts, such as pins, rivets, washers, nuts, catheters, barometer springs, screens, radiator parts, etc. 

3. used for complex cold punching parts and deep punching parts, such as radiator shells, conduits, bellows, shells, gaskets. 

4. for condensing and heat dissipation tubes, siphon tubes, snake-shaped tubes, cooling equipment parts. 

5. used for water supply and drainage pipes, medals, artworks, water tank belts and bimetallic sheets.
