    GUN SIGHT STEEL

    Just thought I would get the opinions of some Materials Engineers, What Steel do you feel would be the best for Firearm Pistol sights?

    Brass Burner Bell Material?

    AMPCOLOY 940 Looks good, Ill have to price it out though. Most companies I can tell are either stamping sheets, or casting, and possibly machining the casting. Currently I am just going to machine the part on a lathe and mill, so extruded bar stock is needed.

    Brass Burner Bell Material?

    Every manufacture is using some type of Brass or Copper Alloy, there are a couple reasons. Aluminum would be good due to high thermal conductivity and light weight, but has a low melting point, wont work. Titanium is light weight but, has a low thermal conductivity and is expensive. Brass/Copper...
