Embodiment 1

[0018] A tin-based alloy with high modulus of elasticity and solidification characteristics of Lima alloy. In terms of weight percentage, the composition of the alloy is B:0.5wt.%, Mo:0.3wt.%, In:2.0wt.%, Sb:2.0wt.%, Mg:3.0wt.%, Cr:2.0wt.% , Co: 3.0wt.%, Al: 15.0wt.%, and the balance is tin. The above-mentioned tin-based alloy with high elastic modulus and solidification characteristics of Lima alloy comprises the following steps: adding the raw materials in the above ratio into an induction furnace under an argon environment, and using a graphite crucible; keeping the temperature at 400 degrees during smelting 10 minutes, rely on high-frequency induction furnace to stir evenly; after stirring evenly, keep warm at 400 degrees for 1 minute and cast out of the furnace; alloy casting uses a steel mold with a diameter of 20-30mm, and uses water cooling to cool down. The obtained ingot is heated to 400-450 degrees at room temperature and kept for 10 minutes; then the melt is poure...

Abstract

The invention discloses high elasticity modulus tin base alloy with solidification characteristics of Lima alloy. The alloy comprises the compositions of, by weight, 0.5-0.6wt.% of B, 0.3-0.5wt.% of Mo, 2.0-3.0wt.% of In, 2.0-2.5wt.% of Sb, 3.0-3.5wt.% of Mg, 2.0-2.6wt.% of Cr, 3.0-5.0wt.% of Co, 15.0-18.0wt.% of Al and the balance Sn. The tin base alloy provides a new alternative material withoutcopper but with the same casting property for the Lima alloy for bronze statue casting in Tibetan areas in China. The implementation and industrialization of the tin base alloy can effectively promote the renewal of new materials and industrial upgrading needs of China's religious ornament industry in China.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a tin alloy. Background technique [0002] In the traditional culture of our country, bronze Buddha statues are a very special art, and have a very important position in the culture of Tibetan Buddhism. In the process of preparing Buddha statues in Tibetan areas, sand casting method and forging method are generally used to produce Buddha statues. There is a size limit in the production of single casting bronze statues by the Shafan method. When making larger-sized bronze Buddha statues, the method of sub-component casting and forging and combination is adopted. [0003] (1) Sha Fan method. Natural sand is used as the outer model material, and a certain proportion of clay is mixed in the sand to make the sand grains stick together. The sand is put into the sand box and compacted to form a sand fan, which is composed of two parts with the same size. Place the mold of the casting...
