WebOct 12, 2024 · Rockwell B is better for softer steel or relatively hard aluminum. For softer aluminum, you may need to use the Rockwell E scale (1/8-inch diameter ball with a 100 kg load) or the Rockwell F scale (1/16-inch diameter ball with a 60-kg load). Generally, the larger the indenter or the smaller the load, the better a scale will be for soft materials.

How to Test the Hardness of Aluminum
WebThese alloys are tough, hard and durable. Steel has an approximate 4 to 4.5 Mohs hardness, depending on type and alloy. Carbon steel must have a carbon content up to 2.1% by weight. It may also contain a variety of other elements (besides iron and carbon). Carbon steel grows harder (and more brittle) when exposed to high levels of heat.
