What are the characteristics of electro-galvanizing of precision stamping parts in the automotive industry?
The galvanized surface of precision stamping parts is a little bluish white, and the luster is not very bright. Play a decorative effect.
Zinc plating is to coat a layer of zinc metal with a thickness of several microns to ten microns on the surface of electroplated parts. It is an anodic coating for iron bases and has certain electrochemical protection. Galvanized parts have good rust resistance. Due to the electrochemical properties of zinc, it has a “sacrificial” protective effect on the steel substrate; while the corrosion product (basic zinc carbonate) of the zinc layer in the atmosphere is relatively dense, adheres well and is insoluble in water. have a certain protective effect. Therefore, galvanizing is widely used to protect steel and its parts from atmospheric corrosion, especially suitable for mass production of precision metal stamping parts.
The most commonly used material in stamping fabrication is sheet metal, and non-metallic sheet is also used. There are two types of sheet metal: ferrous metal and non-ferrous metal.
Commonly used stamping materials are ordinary carbon structural steel plates, such as: Q195, Q235, etc. Electrical silicon steel plate, such as: DT1, DT2.
High-quality carbon structural steel plate, the chemical composition and mechanical properties of this steel plate are guaranteed. Among them, low carbon steel is used more, and the frequently used grades are: 08, 08F, 10, 20…. The stamping performance and welding performance are good, and it is suitable for making stamping parts with little stress.
Low alloy structural steel plates, commonly used models are: Q345 (16Mn), Q295 (09Mn2). It is suitable for manufacturing important stamping parts with strength requirements.
Stainless steel plates, commonly used are: 1Cr18Ni9Ti, 1Cr13, etc., suitable for manufacturing parts with anti-corrosion and anti-rust requirements.
Non-ferrous metals, such as copper and copper alloys (such as brass), etc., the grades are T1, T2, H62, H68, etc. Plasticity, electrical conductivity and thermal conductivity are good. There are also aluminum and aluminum alloys. The commonly used grades are L2, L3, LF21, LY12, etc., which have good plasticity, low deformation resistance and light weight.
Non-metallic materials, such as glue board, rubber, plastic board, etc.
The shape of precision stamping materials is often made of thin sheets, and special specifications of coils are used for mass production and fabrication. Special block materials can be used, which are more suitable for single-piece small batch production and stamping of expensive non-ferrous metals.
