In the security door lock cylinder, what is the difference between the following types of lock cylinder material, full copper, pure copper, aluminum clad zinc, aluminum clad copper, zinc alloy.
1, full copper
All-copper is a brass raw material mixed with a certain amount of other alloying elements in proportion to the corrosion resistance, strength, hardness and cutting properties of copper have been improved.
2、Pure copper
Pure copper is the highest copper content of copper, because the color purple-red also known as purple copper, the main component of copper and silver, the content of 99.5-99.95%.
3、Aluminum clad zinc
Brass is an alloy of copper and zinc, the mechanical properties and wear resistance are very good.
4、Aluminum clad copper
Aluminum-copper alloy is very hard, melting point is 640 ℃, generally consists of 97% of aluminum and 3% of copper, is room temperature and high temperature mechanical properties, casting process is simple.
5、Zinc alloy
Zinc alloy is based on zinc added to other elements composed of alloys, zinc alloy melting point is low, good fluidity, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, the residual material to facilitate recycling and remelting.
