3003 aluminum coil and sheet is approximately 20% stronger than 1100 series aluminum. 3003 aluminum reacts well to mechanical finishings as well as organic finishes. 3003 welding is readily accomplished by means of conventional welding methods, but may be gummy if machined. Soldering is limited to the torch method.

TW has a wide range of sizes readily available to the AMS 4006 for O temper, AMS 4008 for H14.
