Rockwell scale - Wikipedia

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda ...

Material Hardness - from Types of Hardness to Testing & Units

In Brinell test, a steel ball of 10 mm diameter is used as an indenter to create an impression on the test piece to calculate its Brinell hardness number. The ball is held in place for a predetermined time, usually 30 seconds, and a force is applied on the ball. This force will vary depending on the test metal being measured.
