There are a number of alloys, composed of different metals, which resemble silver, and may be briefly mentioned here.

I

Warne's metal is composed of tin 10 parts, bismuth 7, and cobalt 3. It is white, fine-grained, but quite difficult to fuse.

II

Tonca's metal contains copper 5 parts, nickel 4, tin 1, lead 1, iron 1, zinc 1, antimony 1. It is hard, difficult to fuse, not very ductile, and cannot be recommended.

III

Trabuk metal contains tin 87.5, nickel 5.5, antimony 5, bismuth 5.

IV

Tourun-Leonard's metal is composed of 500 parts of tin and 64 of bell metal.

V

Silveroid is an alloy of copper, nickel, tin, zinc, and lead.

VI

Minargent. Copper, 100 parts; nickel, 70 parts; tungsten, 5 parts; aluminum, 1 part.

VII

Nickel, 23 parts; aluminum, 5 parts; copper, 5 parts; iron, 65 parts; tungsten, 4 parts.

VIII

Argasoid. Tin, 4.035; lead, 3.544; copper, 55.780; nickel, 13.406; zinc, 23.198; iron, trace.
