Do you use metal parts? Do you know about electric performance of metal?
In the electric and electronic industry,we often deal with metal parts. About the metal parts,to say it informally, is processing by gold,silver,copper,brass, steel, stainless steel and so on. Gold and silver are precious metals ,they are usually used in jewelry and Currency. Copper as the envoy of human civilization,has good excellent conductivity ,is the best choice for conductor. The steel is widely used in electric industry. The electric performance of metal is very important standard to choose material.Let us know about electric performance of metal.
1.Metal conductivity
The Metal conductivity is restricted by temperature and humidity.The excellent conductivity plays an important role in metal parts.
2.Metal heat conduction performance
The coefficient of conduction measure heat conduction performance
3.The hardness and ductility of metals
The hardness testing according to different testing methods, has static pressure method( such as Brinell Hardness,rockwell hardness and Vickers hardness),scratching method(such as Moh's hardness),Backjumping(such as Shore hardness).
4.Metal corrosion resistance
The metal corrosion resistance depends on material component, chemical properties.
The wiring terminal belongs to connector,but the metal parts of inside terminal plays an important role. For PCB terminal, in order to more easily to solder in circuit board,our company usually adopt fog tin plating to deal with conductive parts. It both can make sure the stability of conductive parts and more easily make terminal fixing on the circuit board.
