Copper Calcium Master Alloy – Its Best Application And Advantages

Posted by Admin on November, 24, 2022

Why use a master alloy?

Copper-calcium Master Alloys are used as decreasing agents and additives in the metallurgical industry. The collective alloys are CuCa5% and 10%. Heeger Materials delivers high-quality Copper-calcium Master Alloy in numerous shapes of waffle ingot, rod, and shot.

Copper Calcium Master Alloy supplied by the Copper Calcium Master Alloy Supplier is mainly used in the metal industry. The two key applications are composition modification and structure control. These alloys are favoured over pure metals as they are more inexpensive, and save production time and energy as they melt faster in lower temperatures.

Why it is necessary to use a copper-calcium master alloy?

Most pure metals are not appropriate for technical applications. Pure gold, for instance, is very soft; this feature makes it simply workable and is one of the causes of its success in jewellery. Therefore but a jewel made of pure gold would effortlessly bend if treated without too much care and would not have adequate wear resistance.

With the development of technique, jewellery has essential increasingly specialized performance from alloys. This has led to the need to study the use of new elements to be added to valuable metals, which can severely change their characteristics.

What characteristics can a copper-calcium master alloy act on?


A feature particularly requested by users of gold, whose colour can be altered to pink, grey-white or various shades of yellow.


Perhaps the most significant feature is as gold and silver are comparatively soft when in their pure state. The hardness is controlled through the master alloys both openly, making the costly metal capable of undergoing hardening heat treatments.

Size of the crystalline grain

Using some essentials called grain refiners it is possible to make the internal structure of the metal denser, this significantly improves some aesthetic and technological aspects, we talked about it here.


Fluidity is an important factor specifically in investment casting applications. It can be labelled as the ability of a liquid metal to dependably fill an elaborately shaped pattern, such as a grid or filigree.


Again for alloys devoted to investment casting, using some features, it is possible to reduce the interaction between the liquid metal and the internal edge of the investment throughout the casting phase.

The advantages of the master alloy


The main advantage of depending on a master alloy is that the alloy manufacturer has a deep knowledge of the impact of the individual additions on the final result.


Additionally, the producer carries out a selection and control work on the raw materials that permits to have constant results over time.


The weighing of an alloy is easier and faster than that of numerous elements taken individually and the opportunities for error by the operator are reduced.


The fineness of the expensive material achieved is more constant because the casting process is simpler.

Lower loss

Melting the elements separately can lead to a rise in the decrease in the title, when there are elements that evaporate at fairly low temperatures, such as zinc.
