Learn More About CBC Specialty Metals 3003 Aluminum

3003 alloy is an aluminum manganese alloy which is rarely specified as an extruded shape since it is non-heat treatable. It is frequently used in cold worked tempers since the amount of drawing increases its mechanical properties. It can be up to 20% stronger than the 1100 series while still retaining its workability and anti-corrosion properties.
