Alloys. Tin is widely used as both a major and minor ingredient of alloy metals. These applications are summarized in Tables 1, 2, and 3. Phosphor bronzes (Table 3) actually contain very little phosphorus, ranging from 0.03 to 0.50%, and hence the alloys are poorly designated. Tin bronzes is the better term. High-silicon bronzes contain about 2.8% tin low-silicon bronzes about 2.0% tin. Gun metals are tin bronze casting alloys with a 5 10% zinc content. Some wrought copper-base alloys contain tin (1) Inhibited Admiralty metal, 1% fin (2) manganese bronze, 1% tin (3) naval brass, 0.75% tin, (4) leaded naval brass, 0.75% tin. See also Copper.

The goods are treated with manganese chloride, and then passed through an alkaline bath whereby manganous oxide is precipitated on the fibre. A subsequent oxidation by air or by a bath of chloride of lime serves to convert this into peroxide, a bottom of the so-called manganese-bronze being obtained. On passing into an acid solution of aniline, aniline black is precipitated on the fibre in a firmly adherent condition.
