CuAINi ALLOY，Copper Aluminum Nickel Alloy，Shape Memory Alloy

Product Information

SCSMA is a remarkable material manufactured by EBAD from Copper, Aluminum, and Nickel (Cu-Al-Ni). This alloy exhibits significantly enhanced performance over commercially available SMAs. These include:Significantly greater strain recovery (9% vs. 3%)，Much higher transition temperature capability (250°C vs.100°C)，True constant force deflection，Very narrow loading hysteresis，Recovery which is 100% repeatable and complete。SCSMAs are manufactured by “growing” as a single crystal from a melt, by a similar method as that used by the semiconductor industry to fabricate silicon boules. The “grown” material is generally fabricated as a rod but can have a range of cross sections (i.e., solid, hollow, flat, or oval). The material can also be subsequently formed into other shapes by traditional fabrication methods such as grinding, machining, or EDM (Electro-Discharge-Machining). A shape memory alloy (SMA) is a metal alloy that demonstrates pseudo-elasticity and the shape memory effect. The shape memory effect is when a material returns to its pre-deformed shape by heating. These unusual properties are being applied to a wide assortment of applications in a number of different fields including the medical and aerospace fields.

Applications of CuAINi ALLOY

there are several basic types of SMAs, such as Ni-Ti (nitinol), Cu-based, and Fe-based alloys ， All of the above types have advantages and disadvantages, while economical aspects such as the price can be very important for material selection and application. Precisely, the economic effect (low price) is the main advantage of Cu-based SMAs compared with other SMAs. Namely, these alloys (Cu-Al-Ni alloys) can be applied in various industrial fields, especially when high transformation temperatures are required (near 200 °C), thanks to their high thermal stability and high transformation temperatures. The selection for application of this group of alloys is affected by their characteristics such as high transformation temperatures (high thermal stability at elevated temperatures, above 200 °C); high corrosion resistance; high resistance to degradation of functional properties during aging processes; and, last but not least, the reasonable cost. Some of the usual applications include the different types of engineering sectors, such as automotive, aerospace, medical and biomedical, and construction。

Packing of CuAINi ALLOY
