What is the difference between 6000 and 7000 series aluminum?

What is the difference between 6000 and 7000 series aluminum?

7000 series is higher strength, costs a whole lot more, is sometimes difficult to weld, and less corrosion resistant. 6000 series is more machinable, some can be heat treated, is weldable and usually more corrosion resistant.

What is 7000 aluminum used for?

Aluminum alloys Aluminum alloy 6061 and alloys of the 7000 series are most commonly used in the production of bicycle frames (Easton Sports).

What’s the difference between 6061 and 7005 aluminum?

6061 aluminum is cast with magnesium as its primary additive. 7005 aluminum is cast with zinc as its primary additive. 6061 aluminum is cheaper, thus making a bike built from it more affordable. It’s more costly to use zinc as an aluminum additive, making the 7005 series more expensive.

How strong is 7000 series aluminum?

7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy (ultimate tensile strength up to 700 MPa for the 7068 alloy). Most 7000 series alloys include magnesium and copper as well.

What Aluminium alloy is used for bikes?

There are two main aluminium alloys in use in the bike industry today – 6061 and 7005. There will be a further designation indicating the tempering process – often T6 – the alloy has gone through.

What aluminum alloy is used for bicycle frames?

The 6061 aluminium alloy is traditionally used in the extrusion of tubes for bicycle frames, because it suits the application.

What is 7000 series alloy?

What is 5000 series aluminum alloy?

Description. Magnesium is one of the most effective and widely used alloying elements for aluminum, and is the principal element in the 5000 series alloys. These are moderate-to high-strength, non-heat-treatable alloys that are readily weldable and have excellent resistance to corrosion, even in marine applications.
