Aluminum

As performance improvement through weight reduction has become a demand of the times, aluminum is widely used in transportation fields such as automobiles, railway vehicles, aircraft, ships, and containers.. Additionally, taking advantage of its lightness, aluminum is used to enhance the work efficiency of high-speed rotating parts and sliding parts in various machines, and to suppress weight increase when equipment is scaled up, resulting in various benefits.The specific gravity of aluminum is 2.7. Compared to iron (7.8) and copper (8.9), it is about one-third the weight, making it easy to use among metals. .Aluminum is also soft, highly ductile, and easy to process. Furthermore, due to the oxide film formed on its surface, it has good corrosion resistance despite its high ionization tendency.

Alloys for Rolling

① Non-heat-treated alloys: Pure aluminum (1000 series), Al-Mn alloys (3000 series), Al-Si alloys (4000 series), Al-Mg alloys (5000 series)

② Heat-treated alloys: Al-Cu-Mg alloys (2000 series), Al-Mg-Si alloys (6000 series), Al-Zn-Mg alloys (7000 series)

Alloys for Casting

Copper Alloy Products

Copper alloy products refer to items made by processing copper alloys—such as brass (copper with added zinc), phosphorus bronze (copper with added tin and phosphorus), and nickel silver (copper with added nickel and zinc)—into shapes like plate, strip, pipe, bar, and wire through hot or cold plastic working methods such as melting, casting, rolling, drawing, and forging.
These products are highly conductive and have excellent thermal conductivity, durability, and color, making them suitable for a wide range of applications.They are materials in high demand for air conditioning (copper pipe) and electronic components (semiconductor lead frames), among others.Please feel free to contact us.
