1, stainless steel: its strength is greater than zinc alloy and aluminum alloy, with high corrosion resistance and high temperature resistance. In the need for high strength and corrosion resistance, such as medical equipment, food processing equipment, stainless steel is the first choice.
2, aluminum alloy: aluminum alloy has low density, high hardness, good plasticity, widely used in various industrial fields. Need a lightweight and high strength materials, such as automobile manufacturing or aircraft manufacturing, aluminum alloy is the best choice.
3, zinc alloy: melting point of 385 degrees Celsius, much lower than aluminum alloy and stainless steel. Good mobility, easy welding, brazing and plastic processing, corrosion resistance in the atmosphere, residual material for recycling and remelting. Creep strength is low, prone to natural aging caused by dimensional changes. What is needed is a material that is easy to process and recycle, such as toy manufacturing or household goods, for which zinc alloys may be more suitable.
