Brass is an alloy primarily composed of copper and zinc, and it can also include small amounts of other metals to enhance its properties. When considering the tin content in typical brass fittings, the percentage usually ranges from about 1% to 15%, depending on the specific grade of brass and its intended application.

A common formulation for brass fittings includes around 5% tin. The addition of tin improves the corrosion resistance, particularly in environments where fittings may be exposed to moisture and other corrosive substances. Specifically, it enhances the alloy's strength and durability, making it suitable for plumbing applications and other uses where leakage might be a concern.

While it is true that some brass formulations can contain more or less tin, 5% is generally accepted as a standard figure for many common brass fittings. Thus, this percentage reflects the typical composition used in manufacturing, balancing performance characteristics with material costs and availability.
