Copper C103 (T1)
Copper C103 (TU2)
Copper C110 (TU0)
Beryllium Copper
Brass
Brass is an alloy primarily composed of copper and zinc, featuring a distinct golden-yellow luster and outstanding comprehensive properties. Its thermal and electrical conductivity is approximately 20%-30% of pure copper, yet sufficient for general electrical and heat dissipation components. Brass also offers excellent wear and friction resistance, making it ideal for manufacturing gears, bearings, and other friction parts.

Magnesium
Magnesium is a silvery-white lightweight metal with a density of only 1.74g/cm³, making it one of the lowest-density structural metals in industrial applications. It is chemically reactive and easily forms a protective magnesium oxide layer at room temperature, but its corrosion resistance is poor in humid or saline environments. Performance is often enhanced through alloying (e.g., adding aluminum, zinc, manganese) or surface treatments (e.g., micro-arc oxidation).
Alloy Types
Magnesium Alloy AZ31B
Magnesium Alloy AZ91D
Titanium
Titanium is a silvery-gray lightweight metal widely used in chemical, marine, and offshore engineering.
