Embodiment 1

[0018] A gold imitation alloy for coastal Buddha statues with excellent stamping performance and its process. In terms of weight percentage, the composition of the alloy is P:0.01wt.%, Ca:1.0wt.%, Mg:4.0wt.%, Fe:1.0wt.%, Sn:3.0wt.%, Bi:1.0wt.% , Si: 2.5wt.%, the balance is copper. The above-mentioned imitation gold alloy for coastal Buddha statues with excellent stamping performance and its process include the following steps: adding the above proportioned raw materials into an induction furnace in an atmospheric environment, and using a graphite crucible; Minutes, stir evenly by high-frequency induction furnace electromagnetically; after stirring evenly, keep warm at 1200 degrees for 1 minute and cast out of the furnace; alloy casting uses a steel mold with a diameter of 50-100mm, and uses water cooling to cool down. The ingot can be used as a casting raw material for casting in subsequent processes to prepare complex-shaped castings; the final heat treatment process of thes...

Abstract

The invention discloses an imitation-gold alloy with excellent stamping properties for a coastal Buddha statue and a process thereof. The imitation-gold alloy comprises the following components by weight percent: 0.01 to 0.02 percent of P, 1.0 to 1.2 percent of Ca, 4.0 to 5.0 percent of Mg, 1.0 to 2.0 percent of Fe, 3.0 to 5.0 percent of Sn, 1.0 to 1.4 percent of Bi, 2.5 to 2.8 percent of Si, andthe balance of copper. The material provides a cheap and effective scheme for the imitation-gold alloy for the coastal large-sized Buddha statue. By adopting the imitation-gold alloy, not only can theproduction cost be reduced, but also the difficulties in the field can be effectively solved. By virtue of the implementation and industrialization of the material, the economic benefit and the social benefit are remarkable.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a copper alloy. Background technique [0002] Gold is a beautiful and precious metal that has been used by people for thousands of years. As the king of hardware, gold is a metal with excellent chemical, physical and electronic properties. With the rapid development of modern industry and service industry, the requirements for products are getting higher and higher, and gold has high stability that cannot be replaced by other metals. Due to its high temperature resistance and corrosion resistance, gold has also been widely used in the aerospace field. With the application of a large number of aerospace technologies to civilians, the market prospect of gold in these aspects is very promising. For example, a kind of gold-coated glass, which is used in aerospace for ultraviolet protection, can now be used in buildings, which can play a good role in preventing solar radiation and he...
