  • the present invention relates to a metal alloy which can be cast, rolled and soldered and has good tarnish and corrosion resistance.
  • Zinc alloys are the easiest to cast into moulds as compared with steel and aluminum alloys. Presently available alloys are generally not suitable for use for the manufacture of functional and ornamental products as they are not easily soldered, rolled and/or cast. Soldering of one or more parts of the alloy together with common tin/bismuth solder is important as many products are made from a combination of different parts. The colour of the alloy is also an important consideration for most products.

  • the present invention discloses the use of aluminum in the preferable range of 0.75-4.75 % by weight.
  • An alloy with aluminum within this range can be cast using various casting methods. However, the grains of this alloy are rough and the thinner portions of the cast parts break easily. Further, the color of the cast part is dull grey to whitish dull grey with increasing aluminum content. Also, a higher percentage of aluminum with higher passivation protection would make soldering with tin/bismuth alloy difficult.

However, the amount of magnesium used should not exceed 0.09 % by weight as the viscosity of the alloy will be adversely affected. When the molten alloy becomes too viscose, the alloy becomes difficult to cast. Moreover, a higher content of magnesium in the alloy will cause excessive dross formation. Hence, the present invention discloses the use of magnesium in the preferable range of 0.07-0.09 % by weight. An alloy within this range can be cast using various casting methods without rough grains. The color of this alloy becomes a brighter grey with increasing magnesium content.

  • the present invention discloses the use of nickel in combination with zinc wherein the total amount of nickel exceeds 0.05 % by weight. However, the amount of nickel should not exceed 1.5 % by weight, as the molten alloy will become too viscose. It is difficult to cast with high viscosity and the alloy will also become brittle. Hence, the present invention discloses the use of nickel in the preferable range of 0.05-1.5 % by weight. An alloy within this range can be cast using various casting methods. The color of this alloy becomes bright grey with increasing nickel content.
  • the total amount of nickel can be increased to a level not exceeding 6 % by weight when mixed with tin.

  • Tin Tin will improve the solderability and increase the ductility of the alloy.
  • the present invention discloses the use of tin in combination with zinc wherein the total amount of tin exceeds 0.1 % by weight. However, the amount of tin should not exceed 1 % by weight. Higher level of tin will contribute towards increasing the internal corrosion of the alloy. Hence, the present invention discloses the inclusion of tin in the preferable range of 0.1-1 % by weight. The color of this alloy becomes bright grey with additional tin. The level of tin can be increased to 8 % when mixed together with nickel. The solderability values of this alloy are shown in Table 1.
