Embodiment 1

[0017] A tin-based anti-fade and anti-brittle with pure gold luster imitating 24K gold. In terms of weight percentage, the composition of the alloy is P:0.2wt.%, Ti:1.5wt.%, Mo:0.6wt.%, Cu:4.0wt.%, Y:0.4wt.%, Sb:2.0wt.%. ,C:0.1wt.%, the balance is tin. The above-mentioned tin-based anti-fading and brittle fracture has the luster of pure gold imitating 24K gold, comprising the following steps: adding the above-mentioned raw materials into an induction furnace under the atmospheric environment, and using a graphite crucible; Minutes, stir evenly by high-frequency induction furnace electromagnetically; after stirring evenly, keep warm at 500 degrees for 5 minutes 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 obtained ingot is rolled at room temperature, and the amount of reduction in each pass is 10-20%; after every two rollings, the intermediate annealing temperature is 180 degrees, and the tem...

Abstract

The invention discloses a tin-based fade-resistant anti-brittle-fracture with pure gold color imitation 24K gold. The alloy comprises the following components of, by weight, 0.2-0. 4 wt.% of P, 1.5-1.8 wt.% of Ti, 0.6-0. 8 wt.% of Mo, 4.0-6.0 wt.% of Cu, 0.4-0.6 wt.% of Y, 2.0-4.0 wt.% of Sb, 0.1-0.3 wt.% of C, and the balance tin. The invention provides a cheap and fade-resistant tin-based alloywith the color of 24K gold for the decoration industry in China, and the situation that most of the conventional imitation gold alloys are copper-based alloys is broken through. The production cost isreduced, and the problem in the field is effectively solved. It is expected that the implementation and industrialization of the material can obtain good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a tin 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 areas 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 heat in...
