They exhibit very high strength, making them very difficult to form. Series 7xxx are the Aluminum – Zinc – Magnesium and Aluminum – Zinc – Copper alloys.The are mainly used in architectural applications. These heat treatable alloys exhibit great strength, good corrosion resistance, and ease of formability. Series 6xxx are the Aluminum – Magnesium – Silicon alloys.They exhibit a very good combination of high strength, resistance to corrosion, formability, and good weldability. Series 5xxx are the Aluminum – Magnesium alloys.This series has the addition of silicon, thus lowering the melting point and for this reason, it is used entirely for manufacturing welding wire. Series 4xxx are the Aluminum – Silicon alloys.This series is one of the most preferable for forming applications. With an addition of 1% Manganese, these alloys have no significant loss in ductility, good corrosion resistance, and very good formability. Series 3xxx are the Aluminum – Manganese alloys.These alloys have excellent machinability, limited cold formability (except in the annealed condition) and less corrosion resistance than other alloys, which is why they are anodized prior to usage.
Series 2xxx are the Aluminum – Copper alloys. They are very ductile in the annealed condition and have excellent corrosion resistance. Series 1xxx are the Aluminum alloys with 99.00% pure aluminum. In aluminum, we have various designations that all have different chemical compositions, making them applicable in various fields of metal processing. To understand this better, we need to talk about alloys, which is the first factor to consider upon selection. From non-heat treatable 30 to the heat treatable 2024, 60, you have many options from which to choose.īut the question remains the same – which alloy is the best product for bending? There are three factors that contribute to the the answer. Annealed and natural aged tempers are more easily worked than hard tempers and artificially aged ones.Ĭlinton Aluminum offers a variety of products, each covering a wide range of applications and processes. Typically, pure aluminum is more easily worked than the alloys. Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical.ĭepending on designation, alloys go through different heat treatment procedures during production. In high purity forms, aluminum is soft and ductile. “Which aluminum alloy bends the best?” is a a common question customers want the answer to.
