Brinell hardness of linotype
http://www.lasc.us/CastBulletNotes.htm WebThe Brinell hardness test method as used to determine Brinell hardness, is defined in ASTM E10. Most commonly it is used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, e.g., castings and forgings. Brinell testing often use a very high test load (3000 ...

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 ... WebAug 29, 2024 · 1.5 At the time the Brinell hardness test was developed, the force levels were specified in units of kilograms-force (kgf). Although this standard specifies the unit of force in the International System of Units (SI) as the Newton (N), because of the historical precedent and continued common usage of kgf units, force values in kgf units are …
WebLinotype (86% lead, 3% tin, 11% antimony, BHN 22) is a eutectic alloy with a low melting temperature and excellent fill properties. It is quite resistant to shrunken bullet syndrome, but it is prone to voids in or near the base of heavy bullets. ... Bullet Hardness is an ongoing debate.

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.
