What is the difference between 7075 and 6061 aluminum?

What is the difference between 7075 and 6061 aluminum?

6061 nearly always has the edge over 7075 when it comes to fabricating the two aluminum alloy types. This is mostly due to 6061 having a lower hardness and tensile strength. The lower hardness allows it to be machined more easily than 7075. The lower tensile strength means that 6061 is easier to form than 7075.

What is the best quality aluminum?

Quick Reference Chart – Choosing an Aluminum Grade

Formability or Workability Weldability
Alloy 3003 Excellent Excellent
Alloy 5052 Good Good
Alloy 6061 Good Good
Alloy 6063 Good Good

Which Aluminium alloy is best?

Alloy 6061: The most versatile of the heat-treatable aluminum alloys, while keeping most of the good qualities of aluminum. This grade has a great range of mechanical properties and corrosion resistance. It can be fabricated by most of the commonly used techniques and it has good workability in the annealed condition.

How strong is 6061 aluminum?

6061-T6. T6 temper 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa).

Is 6061 aluminum corrosion resistant?

Aluminium alloy 6061 is a medium to high strength heat-treatable alloy with a strength higher than 6005A. It has very good corrosion resistance and very good weldability although reduced strength in the weld zone. It has good cold formability in the temper T4, but limited formability in T6 temper.

Can you machine 7075 aluminum?

Aluminum 7075 Machining It possesses great cracking resistance and increases in strength as temperature decreases, making it ideal for the aerospace industry. Aluminum 7075 has a machining cost factor of 0.9 when compared to steel 12L14. It can be forged and heat treated, but is not ideal for welding.

Is 6061 aluminum machinable?

6061 aluminum is one of the most versatile of all the aluminum alloys because of its clean surface finish and good mechanical properties including strength, formability, weldability, machinability, and corrosion resistance.

Which is better 6061 or 7075 aluminum alloy?

7075 is notable for its high strength-to-weight ratio and improved strength over 6061. Because of this, 7075 is largely used in aerospace, marine and transportation industries. Any industry where high strength and light weight properties are critical, this alloy is preferred.

What is the chemical breakdown of 7075 aluminum?

Its nominal chemical breakdown is 90.0% Al, 5.6% Zn, 2.5%Mg, 0.23%Cr, and 1.6% Cu. Because 7075 has >1% Cu, it is more affected by caustic environments and does not share the high corrosion resistance which other aluminum alloys have.

What is the elemental composition of 6061 aluminum?

Type 6061 aluminum is from the 6xxx class of aluminum, which include those alloys that use magnesium and silicon as their primary elements. The elemental composition of 6061 aluminum alloy is as follows: 0.6% Si, 1.0%Mg, 0.2%Cr, 0.28% Cu, and 97.9% Al.

Is the yield strength of 6061 aluminum weak?

However, 6061 alloy is not to be thought of as weak, as a yield strength of 276 MPa is only slightly less than some low carbon steels. The modulus of elasticity is a measure of a material’s resistance to permanent (or “plastic”) deformation. It is useful as a means of defining the “stiffness” of a material.
