Phosphor bronze is an alloy of copper, tin and phosphorus - 0.5–11% tin and 0.01–0.35% phosphorus.
The tin strengthens the alloy by increasing its corrosion resistance. The phosphorus contributes by increasing the wear resistance and stiffness of the alloy.
These alloys become special in their utility. It is unmatched it its toughness, strength, low coefficient of friction, and fine grain. The phosphorus reduces the viscosity of the molten alloy, which makes it easier and cleaner to cast and reduces grain boundaries between crystallites.
Aerospace CSK Screws
100 Degree screw
Countersunk Screws (Also know as a flat head screw) are used where the finished surfaces require a neat and flush fastening unit. The countersunk portion offers good centering possibilities.
100° special flat head screws have been developed for use In soft materials to distribute pressure over a larger and less angular surface. Very well adapted for use with thin aluminium, soft plastics, etc. MIL-STD-1515 "Fastener Systems for Aerospace" requires 100 degree countersunk screws.
