Metal material

The metal materials used in plastic retro square sun frames are copper alloy, nickel alloy and precious metal.

Require a certain degree of hardness, softness, flexibility, abrasion resistance, corrosion resistance, light weight, luster and good color. Therefore, the metal materials used to make plastic retro square sun frames are almost always alloy or used after metal surface treatment.

1. White copper frame (copper zinc alloy) :

The main components are 64% copper, 18% zinc, 18% nickel. The cheapest and easy to process electroplating of the frame materials is mainly used for manufacturing hinge bracket, small parts and low-grade frame.

2. High nickel alloy frame

The content of nickel is up to 80%, mainly including nickel chrome alloy, manganese nickel alloy, etc., the corrosion resistance of high nickel alloy is better.

3. Monel frame

Nickel-copper alloy, the content of nickel reaches 63% of copper and about 28% of copper, in addition, there are a few other metals such as iron and manganese, especially: anti-corrosion, high strength and strong welding, which are the most used materials for the middle frame.
