lead casting hardness test|how to check lead hardness : dealers This describes a method for the determination of lead alloy hardness. It is a simple, quick, and economical means to test hardness of unknown alloys, and I have found it to be reliable and accurate. The reaction takes place at 428 Farhenheit (240-degree Celsius) maximum in the Teflon-lined autoclave, whereas 392 Farhenheit (200-degree Celsius) is the safe temperature.1. Do not operate the autoclave without water. Avoid using hard-water in the unit. 2. Clean Teflon reaction vessel properly before use to avoid contamination. 3. Do not put any extra weight on the autoclave. 4. Close the autoclave caps properly, never try to open it by force without first .

I have one really good recommendation for a hardness tester that provides the most versatile testing of lead alloys. It can be used with cast bullets, ingots, slabs, etc. It gives a BHN hardness result, which can be directly referred to.A 5-minute video covering the basics of cast bullet hardness and demonstrating Lee Precision's Lead Hardness Tester. I just got my new LBT hardness tester and gave it a trial run. Very easy to use and the results seems very consistent. I thought about getting the Lee tester which is cheaper but I didn't want to do a magnified check and interpretation of results. The LBT gives a direct BHN readout and is fast as well.Brinell hardness testing is extensively used in the casting industry to assess the hardness and quality of cast materials, such as cast iron, aluminum alloys, and bronze.
