What is the Brinell hardness of aluminium?
15 HB
It is one of several definitions of hardness in materials science….Common values.
| Material | Hardness |
|---|---|
| Lead | 5.0 HB (pure lead; alloyed lead typically can range from 5.0 HB to values in excess of 22.0 HB) |
| Pure Aluminium | 15 HB |
| Copper | 35 HB |
| Hardened AW-6060 Aluminium | 75 HB |
What is the Brinell hardness of 6061 aluminum?
95
Aluminum 6061-T6; 6061-T651
| Physical Properties | Metric | English |
|---|---|---|
| Hardness, Brinell | 95 | 95 |
| Hardness, Knoop | 120 | 120 |
| Hardness, Rockwell A | 40 | 40 |
| Hardness, Rockwell B | 60 | 60 |
What is a good Brinell hardness number?
Brinell numbers for commonly used metals range from HB 15 to 750. Typical values include: Pure aluminum = 15. Mild steel = 120.
Does aluminium have hardness?
Pure aluminium is quite soft and lacking in strength. In most applications various aluminium alloys are used instead because of their higher strength and hardness. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.
What is the HRC of aluminum?
Hardness of homogenized and SHRQ samples increased to a maximum value of 51.2 HRC and 47.4 HRC, respectively, at 10 wt. % of steel dust in the aluminium alloy. The tempered composite samples have 54.1 HRC at 5 wt. % steel dust and 47.7 HRC at 15 wt.
What does a high Brinell number mean?
In this case, the ultimate tensile strength (in psi) approximately equals the Brinell Hardness Number multiplied by 500. Generally, a high hardness will indicate a relatively high strength and low ductility in the material.
Where is aluminum on the hardness scale?
Aluminum: 2.5-3. Copper: 3. Brass: 3. Bronze: 3.
How do you test the hardness of aluminium?
The most common type of hardness test is the Rockwell test. The Rockwell test encompasses a set of tests for different hardness ranges. The Rockwell B (HRB) scale is used for aluminum and structural steels (softer materials) while the Rockwell C (HRC) scale is used for high carbon alloy steels (harder metals).
