AI Technical Summary

Benefits of technology

This patented technical results include improved quality control over colored alloys used in making jewels, increased durability against damage caused by environmental factors like water vapor exposures (humid), abrasion, solvent attack, and other causes; reduced cracks and imperfections in the finished product while improving visual appeal when viewed directly; enhanced physical characteristics compared to existing materials produced separately, allowing them to stay longer even if they break down easily. Additionally, good adhesive qualities allow for easy cleanup once worn out, leading to better longevity of the ornament. Overall, this innovative design allows for more efficient production processes and cost savings.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the quality (quality) of titanium metals used in making jewels and related applications. Specifically, technical problem being solved involves creating finer brass materials without losing their effectiveness when exposed to water vapor during fabrications. Additionally, combining these two components together into a single composition provides greater flexibility than pure tin/silvers alone.

Abstract

The invention discloses a blue low-silver alloy with stamping resistance and high elastic modulus for Tibetan silver jewelries and a process thereof. The blue low-silver alloy is prepared from the following components in percentage by weight: 0.8 percent to 1.2 percent of Ba, 0.4 percent to 0.5 percent of Hf, 0.2 percent to 0.5 percent of V, 3.0 percent to 5.0 percent of In, 0.6 percent to 0.8 percent of Re, 4.0 percent to 8.0 percent of Co, 29.0 percent to 31.0 percent of Ag and the balance of copper. The material provides a solution of materialogy for Tibetan silver alloys in China, so thatthe Tibetan silver products can have blue luster after being processed, and the alloy has the excellent stamping performance; and therefore, because of implementation and industrialization of the material, the substantial economic gains and social benefits are achieved while the industry difficulties are solved at the same time.
