Aluminium bar is produced to international aerospace specifications in a wide variety of alloys. Physical and mechanical properties vary a great deal depending on the alloy and the heat treatment employed, making correct product selection critical. Stocks are carried in a range of sizes selected to best match the requirements of current aircraft build programmes.
