Zinc-alloy strip is a kind of ideal alloy product made of zinc-aluminum alloy. Its mechanical properties close to brass, can be used for higher cutting speed and deeper cutting. Zinc-aluminum alloy suitable for a variety of plating process, plating copper, nickel, chromium, tin, silver and ternary alloy, etc.
What are the major properties of zinc alloy
Feature 1- good machining performance
Fast cutting extruded zinc-aluminum alloy is easy to be (turning, milling, drawing, planing, drilling, etc.) cutting, and its comprehensive performance is close to that of lead brass. The alloy can be cut with higher cutting speed and deeper cutting capacity. And processed parts of high finish and precision, high processing efficiency.
Feature 2- Good surface treatment effect
Zinc-alloy strip is suitable for a variety of electroplating processes. The finished products have no pitting and bubbles, and the surface finish is similar to that of copper plated products. There is no obvious corrosion in 48 hours of neutral salt spray test, and the electroplating yield can reach more than 98%.
Characteristic 3- cold working properties close to lead brass
Mechanical properties close to or even exceed lead brass, compressive strength 400~470 MPa, hardness 100-140 HV, elongation 15-24%. Cold bending 90 degrees wrinkle free 220℃ - 26 red punch easy forming no cracking no porosity no sand hole, torsion test can meet most industry standards.
Characteristic 4- Good conductivity
Conductivity is similar to H62, conductivity > 28% (IACS), more than ordinary H59 and other lead brass, has a broad application prospect in electronic, electrical, electrical and other industries.
Characteristic 4- High cost performance
Using quick-cut extruded zinc-aluminum materials, the cost of the same finished work piece is only 40% of the cost of lead brass.
Zinc-aluminum alloy in which categories of applications
1. Metal pen: pen tip, lift first class;
2. Rf connectors: all kinds of low-frequency connectors shell, part of the inner conductor, etc.
3. Electrician: electrical plug, needle, etc.;
4. Lamps and lanterns: wiring terminals, etc.
5. Lock: lock core, lock body and stamping accessories;
6 capacitor: rotating shaft, etc.;
7. Hardware spare parts: such as nuts, screws and various standard parts of different specifications.
