Rigid ALuminum Busbar-No Surface Treatment

01-Introduction of the Rigid Aluminum Busbar

Ø Rigid aluminum busbar are mainly made of aluminum alloy plate, which have lower costs compared to copper bars, but lower conductivity.

Ø Rigid aluminum busbar are suitable for electrical connections with low current and low power, and are commonly used in cost sensitive but low current demand situations

02-Advantages of rigid aluminum busbar to rigid copper busbar

Ø The weight of aluminum bars is relatively light, which can save human and material resources during installation and transportation

Ø The relatively low price of aluminum makes it more cost-effective

Ø Aluminum is prone to form a dense layer of aluminum oxide protective film in the air, which can prevent further oxidation of the internal aluminum. Therefore, it exhibits good corrosion resistance in outdoor environments, chemical equipment, and other occasions.However, in certain extreme environments, such as high temperatures or highly corrosive media, aluminum's corrosion resistance may not be as good as copper's

03-Rigid aluminum busbar-Manufacturing process

Ø Aluminium sheet material thickness 0.8mm to 18mm

Ø Conventional material: Al1060-O Al1060-24

Ø Forming process: Laser cutting,Wire cutting,Stamping, CNC bending,CNC machining

Ø Connection method-bolt/nut connection or laser welding

Ø Rigid Aluminium busbar plating process-nickel/tin/silver plating

Ø Application: Cell connection and Module connection of the battery pack
