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. 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. Homemade Lead Harness Tester. I work in a machineshop and I was able to come in after hours and fabricate a lead harness tester based on a short article in the Lyman cast bullet handbook 3rd edition. I will have a drawing and photos posted shrortly.The best hardness test method and corresponding load depend on the material to be tested, the component shape, applica- tion, and the customer requirements. After process of elimination, there are often only a few options left.
The cheapest way to do this is with the Lee Lead Hardness Testing Kit. It measures the “Brinnell” hardness of the alloy, which is simply a hardness scale relative to itself, and people have figured over the years how much pressure this hardness scale can correlate to. The hardness of a lead affects its strength, smoothness, smudge resistance, and pigmentation. Writers can use different lead grades to make their lines lighter or darker, while an artist can employ the full range of lead grades to achieve different effects.A 5-minute video covering the basics of cast bullet hardness and demonstrating Lee Precision's Lead Hardness Tester.
