It can also be selectively dyed. The gold plating process (taking electroplating gold as an example) first pre-treats the substrate (such as nickel plating of copper alloy to prevent diffusion, stainless steel activation), flashes gold to enhance bonding strength, then electrolytically deposits the gold plating layer in the gold plating solution, and finally washes and anti-discoloration treatment to maintain the gloss and prevent corrosion of the bottom layer.

• The design of gold metal parts is exquisite and complex, with a square body, parallel stripes on the surface or to enhance heat dissipation/strength, a cylindrical protruding structure on one side or for connecting and transmitting signals, and small holes in the four corners for easy installation and fixation.
• Its surface is smooth and the details are fine, and it is likely to be processed by CNC to ensure accuracy.
• The gold appearance is anodized or gold-plated, which is both beautiful and corrosion-resistant.

This component is commonly found in electronic equipment and can be used as a heat dissipation module, signal transmission component or precision instrument support structure. With its heat dissipation, connection and fixing functions, it ensures stable operation of the equipment and is widely used in fields with high requirements for precision and performance.

6061 aluminum alloy has good mechanical properties and processing properties, moderate strength and easy forming. It is suitable for occasions with high requirements for structural strength and lightweight, such as robotic arm components of automation equipment; 7075 aluminum alloy is often used in aerospace, high-end military industry and other fields with strict requirements on material properties due to its ultra-high strength and hardness, and can withstand high-intensity stress in extreme environments.
