Western white copper:Good shielding effect, relatively soft, more expensive than stainless steel, easy to tin, currently most shielding covers are made of phosphor bronze

Stainless steel: good shielding effect, high strength, moderate price; But tin plating is difficult (it is almost impossible to tin without surface treatment, and nickel plating can improve it, but it is still not conducive to surface mounting)

Tinplate: The shielding effect is the worst, but the tin coating is good and the price is cheap

Tin bronze: slightly inferior shielding effect, tin plating situation to be investigated

Brass: slightly poor shielding effect, tin plating situation to be investigated

In the material analysis of the above products, due to its good shielding effect, good corrosion resistance, and good welding performance, although more expensive than stainless steel, most of them use phosphor bronze as the raw material for shielding covers. The following mainly introduces the composition of white copper:

Yangbai Copper is a copper based alloy with nickel as the main alloying element, named after its silver white color. Copper and nickel can infinitely dissolve into each other to form a continuous solid solution. Adding nickel to copper can significantly improve corrosion resistance, strength, hardness, resistance, and reduce the temperature coefficient of electrical resistivity. In copper alloys, white copper is widely used as a corrosion-resistant structural component in industries such as mobile phone signal shielding, electronic products, shipbuilding, petroleum, chemical, power, precision instruments, and medical equipment due to its excellent corrosion resistance and ease of plastic processing and welding. Some white copper also has special electrical properties, which can be used to make resistance elements, thermocouple materials, and compensation wires.

The above are the advantages and disadvantages of selecting several commonly used materials for shielding covers. White copper is currently the most widely used in the market, and due to price and product requirements, stainless steel and tinplate are also widely used in the market.
