What are the differences between 6001 and 6003 aluminum alloys?

The difference between 6061 and 6063: The mechanical properties of metal profiles include hardness, strength, ductility, plasticity, fatigue resistance, yield strength, etc. 6063 aluminum alloy is better than 6061 aluminum alloy in plasticity and can meet high precision requirements. In terms of strength and processing performance, 6061 aluminum alloy is better than 6063 aluminum alloy.

1.Different element density

The main alloying elements of 6063 are magnesium and silicon, with a density of 2.69g/cm³, containing 0.4%Si and 0.7%Mg, hard material strength 295Mpa, soft material strength 111Mpa, melting temperature 615-655 degrees.

The main alloying elements of 6061 are magnesium and silicon, and form Mg2Si phase. The composition contains 0.6% Mg, 0.25% Cu, 1.0% Mg, 0.09% Cr, hard strength 316Mpa, soft strength 127Mpa, in Mg2Si, Mg/Si ratio is 1.73, in the heat treatment state, Mg2Si is dissolved in aluminum, so that the alloy has artificial aging hardening function.

2.Respective advantages:

6061: strength, weldability, high corrosion resistance

6063: excellent weldability, extrudability and electroplating, good corrosion resistance, toughness.

3.Application range

6063 is mainly used for: tubular railings, furniture, frames, construction extrusion profiles

6061 is mainly used for: manufacturing trucks, tower buildings, ships, trams, furniture, mechanical parts, precision machining, etc. tubes, rods, profiles, plates.
