Aluminium alloy with excellent laser weldability

The invention provides an aluminum alloy plate with excellent laser weldability which can get better fusion state even under low output power. The aluminum alloy plate is characterized in that aluminum alloy contains 0.6%-10% of Si, less than 0.2% of Cu, less than 0.2% of Mg, and balance of aluminum...

More Information
Summary:The invention provides an aluminum alloy plate with excellent laser weldability which can get better fusion state even under low output power. The aluminum alloy plate is characterized in that aluminum alloy contains 0.6%-10% of Si, less than 0.2% of Cu, less than 0.2% of Mg, and balance of aluminum and unavoidable impurities; and number of Si single-phase of 2mum-5mum and intermetallic compound in per 10000mum is more than 40.
