Brinell hardness of linotype
WebFor plain carbon steels, the approximate relationship between the hardness and tensile strength is: Tensile strength = Bhn × 515 (for Brinell numbers up to 175) Tensile strength = Bhn × 490 (for Brinell numbers larger than 175) The above formulas give the tensile strength in pounds per square inch for steels. WebHardball Bullet Casting Alloy consists of 2% tin, 6% antimony and 92% lead. This modern version of the old Lyman #2 is an excellent all-around alloy for most handgun bullets and many higher velocity rifle cartridges. The Brinell Hardness of Hardball Alloy is about 16. Sold in ~5 pound ingots. Ingots are approximately 8-3/4" x 1" x 2" and weigh ...

WebIn the intervening years, extensive experimentation has revealed the empirical correlation of 3 x 480 x Brinell Hardness Number (BHN) (or more simply, 1440 x BHN) as an estimate of the minimum peak pressure required for bullet obturation (the reason for the "3 x 480" format is the number "4 x 480" also has significance, and this format makes it ... WebThere are a number of ways to measure hardness, but most reloaders use the Brinell Hardness Number (BHN). Lead is a very soft metal, and has a BHN of 5, silver is much harder, with a BHN of 24.5. ... In fact, some of the lead alloys being used are very nearly as hard as pure silver. Linotype, for example, is a commonly used "hard lead" alloy ...
WebNov 17, 2008 · I saw a old post where someone was using hard lead ( wheel weights ) bullets in his smith. Anyone having good results in your smith with hard lead ? if so what ratio of lead to wheel weights are you using? With scrap lead getting harder to find and more costly, I started using much cheaper hard lead in my smooth bore with good results.
