Aluminum copper investment castings use the nonferrous metals of aluminum and copper. The term nonferrous means that the particular metal under discussion does not contain iron. Both aluminum and copper investment castings can be created with alloys rather than the pure metals.

Aluminum Investment Castings

Aluminum is the most commonly used nonferrous metal for investment casting purposes. Aluminum is a lightweight metal. Products and parts made with aluminum are appropriate for use in a wide variety of applications, including aviation, electronics, pump and valve housings, and military equipment.

Aluminum Copper Investment Castings as Alloys

Aluminum copper investment castings are created using the base metals of either aluminum or copper. Both aluminum and copper can be cast in their pure forms, although it is more common for them to be used as the base material for a number of different alloys.

Common aluminum alloys include some combination of aluminium, silicon, and/or magnesium. These substances can increase the corrosion resistant properties of aluminium and result in stronger products than those made with aluminium alone. Aluminium alloys are frequently used to create aircraft components and parts.

Copper Investment Castings

Copper is also widely used for nonferrous investment casting. Copper is known for being particularly resistant to corrosion and oxidation. Therefore, copper is often selected to produce products that will be in environments in which other metals might easily become corroded and subject to oxidation damage. Additionally, copper is known to be highly conductive, and is often selected for electrical and electronic components.

Copper investment castings frequently include the element beryllium, which is added to the copper to help strengthen and harden the malleable substance. Alloys consisting of copper and beryllium have many desirable characteristics. They are highly conductive, resistant to corrosion and fatigue, and are both hard and strong. Copper-beryllium alloys are frequently used to create springs, electrical contacts, electrodes for spot welding, and other products.

Many Purposes for Aluminum Copper Investment Castings

Both aluminum and copper are very malleable metals that are commonly used to create investment castings. While both these types of metals are nonferrous, there are many differences between the two. It is important to understand the differences when choosing between aluminum copper investment castings.
