Calcium Alloys

Calcium alloys are an important compound used in several large scale manufacturing processes. Although there are many permutations for creating calcium alloys, the main types produced are Lead Calcium Alloy, Lead Calcium Tin Alloy and Magnesium Calcium Alloy. Small amounts of copper or sulphur are often added to improve the casting properties and make the alloy less corrosive. Other, less common calcium alloys include Calcium Aluminium Alloy and Calcium Silicon Alloy.

Originally research into calcium alloys began in 1975, and between 1975 and 1980 the production of calcium alloys was underway. Calcium alloys of this kind are primarily used in the manufacturing of batteries and other electrical components that require similar electrodes.

Calcium alloys exhibit a fairly low mechanical strength. However, considering the applications for which they are mostly used (internal parts for large batteries), this is not usually an issue. The actual grain structure of calcium alloys, which are produced during the manufacturing process, is what makes them such a good anti-gassing compound when used in battery production. Most calcium alloys are also fairly lightweight and have a very high thermal resistance. The primary property of calcium alloys is exceptional energy transfer capability. Good quality calcium alloys can conduct electricity very efficiently.


A very large percentage of the global calcium alloy supply is manufactured in developing economic nations such as China and India, although a significant quantity is also produced in the USA. Calcium alloy is produced by combining calcium with one of several secondary materials, which include magnesium, lead, tin and aluminium. Typically, the alloy produced will be cast into small ingots, which can then be added to a further manufacturing process quite easily. Actual quantities sold are quite small, as only a small amount of calcium alloys are used in the manufacturing process of the primary items made from it, namely deep cycle batteries.


Calcium alloys such as tin calcium alloy and lead calcium alloy are primarily used in batteries, or other electrical equipment which requires a compound with exceptional energy transfer properties. The main use of calcium alloys is in the manufacturing of electrode grids in automotive batteries. Until several decades ago, antimony was used to manufacture these electrode grids, but during the early 1980s, calcium alloys became the materiel of choice for battery manufacturers. This resulted in longer lasting batteries, which discharge more evenly, and are able to be recharged many more times than the older antimony type batteries.
