NettetVickers hardness of Aluminium is approximately 167 MPa. Scratch hardness is the measure of how resistant a sample is to permanent plastic deformation due to friction from a sharp object. The most common scale for this qualitative test is Mohs scale, which is used in mineralogy. NettetThe test is done by measuring the surface area of the indentation created by a diamond in the shape of a square-based pyramid. The HV number equals the force divided by the area (F/a). Carbide grades are usually in the range of 1,300-1,900 HV. Ceramics can reach a hardness of 2,000 HV, CBN up to 3,000 HV, and PCD up to 6,000 HV

NettetIt is impossible to define a single conversion method using different hardness test methods. That’s why these standards formulate tables for conversion process, with test … NettetStrength: 300 Mpa Hardness: 95 HB Average Machinability Rate: 270% Aluminum Alloy Series 7xxx The main alloying element in the 7xxx series is zinc, but it also contains copper, chromium, and magnesium. It has much higher strength and hardness than 2xxx and 6xxx but has a lower machinability rating and costs more. hid headlight assembly for 2010 cadillac srx
