The company takes advantage of the unique celestine resources of tongliang and dazu, and learns from the advanced production experience of strontium carbonate at home and abroad to design a more scientific and reasonable production process. The company mainly produces strontium and strontium aluminum alloy, with an annual output of 2000 tons of strontium and 5000 tons of strontium aluminum alloy. Strontium metal is widely used in electronics, metallurgy, chemical industry, aviation, automobile and other industrial fields. Strontium aluminum alloy is widely used in automobile, motorcycle aluminum wheel hub, automobile engine cylinder, aircraft alloy casting. As countries pay more attention to greenhouse gas emissions and automobile exhaust emission standards are continuously improved, more and more new technologies and new materials are applied in automobiles. Strontium and strontium aluminum alloy are lightweight materials. The use of strontium and strontium aluminum alloy in automobile wheel hubs can reduce the weight of the automobile itself, thus reducing consumption and emission, effectively promoting energy conservation, emission reduction and sustainable development, and playing a protective role for the environment.
