The Lee Lead Hardness Test Kit is a component for your reloading equipment. It offers a quick and easy way to determine the exact Brinnell Hardness Number of an alloy. It will save you time and components by ensuring you dont work with the wrong alloy. FEATURES.The Brinell hardness testing method is used in various cases where large or rough surfaces, coarse-grained materials, or high loads are involved. It is particularly well-suited for testing the hardness of materials with relatively low hardness ranges, such as non-ferrous metals, castings, and softer steels.
This is the start of a series of videos regarding alloy hardness. I'd like to share my technique with you regarding how I use the Lee Hardness Tester. If you. One of those articles is a comparative test of most of the common lead hardness testers. Participants did blind tests of sample bullets all cast in the same lot. I was one of the LBT testers using a 30 year old tool that agreed well with the standard results. The standard result was from a calibrated commercial brinell test machine in a metals lab.The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.Find many great new & used options and get the best deals for LEE PRECISION Lead Hardness Test Kit - 90924 at the best online prices at eBay!
