Detailed Product Description

Alloy AA 6061

Description of Alloy

Alloy 6061 is a well proven medium strength structural alloy that satisfies the requirements of a number of specifications in extruded shapes. It is treated as an equal alternative to AA 6351 and has a long history in furniture, handrails, transportation, industrial equipment and general structures.

Characteristic

Welding	Alloy 6061 is readily welded by the MIG and TIG processes. Recomended filler alloy is 5356
Machining	Readily machined in all tempers given
Forming	All tempers may be formed, the softer tempers accepting more severe forming.
Corrosion	Excellent resistance to the atmosphere, fresh waters, many soils. Fair resistance to
	seawater. Good general corrosion resistance in structural application.

Temper Available (Extrude Shaped T4,T6)

T4	Solution heat treatment followed by natural aging at room temperature to a substantial stable condition.
T6	Solution heat treatment followed by artificial aging.

Chemical Composition

Alloy 6061 is a heat-treatable aluminium-magnesium-silicon alloy. Reffering to Standard JIS 4100
