Naval brass, similar to admiralty brass, is a 40% zinc brass and 1% tin. Red brass, while not technically brass, is an American term for CuZnSn alloy known as gunmetal. Rich low brass contains 85% copper 15% zinc often used in jewelry applications . White brass contains more than 50% zinc and is too brittle for general use. Yellow brass is an ...

Gray iron is a common engineering alloy because of its relatively low cost and good machinability, which results from the graphite lubricating the cut and breaking up the chips. It also has good galling and wear resistance because the graphite flakes self-lubricate.
Graphite. Used in air compressors, food industry, railway track joints, brass instrument valves, piano actions, open gear, ball bearings, machine-shop works, etc. It is also very common for lubricating locks, since a liquid lubricant allows particles to get stuck in the lock worsening the problem. It is often used to lubricate the internal ...
It is self-lubricating, a good electrical insulator, tolerant to fairly high temperatures, and has low out-gassing. It is not suitable for barrier between vacuum and atmosphere, as it is somewhat permeable for gases. Ceramics is a superior choice, however. [3] Polyethylene is usable but requires thorough out-gassing.
Dogs should wear shoes when the stuff they’re walking on will do significant damage to bare feet. Canine paw pads are designed for the outdoors and can weather a lot of, well, weather. It’s ...
Boundary lubrication is defined as the regime in which the load is carried by the surface asperities (high points) rather than by the lubricant. [7] This is the effect that makes Ultra-high-molecular-weight polyethylene "self-lubricating". Boundary film lubrication: [8] The hydrodynamic effects are negligible. The bodies come into closer ...
The majority of people love bringing a lubricant into the bedroom to make sexual activity more enjoyable and reduce pain during vaginal penetration with fingers, a penis or sex toys, says Dr. Ross.
