Nickel titanium cold-rolled tube is a type of tube made of nickel titanium alloy processed through cold rolling technology, with unique properties and wide applications. Here is a detailed introduction about it:

1、 Definition and Material Characteristics:

Nickel titanium cold-rolled tubes are made from nickel titanium alloy as raw material, with a main component of nickel and titanium in an atomic ratio of approximately 50:50, which can be adjusted according to demand. This alloy has shape memory effect and superelasticity, which means that within a certain temperature range, the pipe can remember its original shape. When deformed by external force, it can return to its original shape when heated or removed, and can also withstand significant elastic deformation without permanent damage.

2、 Production process:

Firstly, high-purity nickel and titanium are proportioned and melted into ingots through vacuum induction melting or vacuum consumable arc melting. After homogenization annealing and surface treatment, the ingots are heated to 600-900 ℃ for hot extrusion to produce hollow tube billets. Then hot rolling or hot drawing is carried out to further reduce the diameter and wall thickness, and annealing treatment is required after each processing. Then, cold drawing or cold rolling is carried out at room temperature to obtain precise dimensions and good surface quality through multiple passes of processing. During the processing, the deformation of each pass should be controlled, and periodic intermediate annealing should be performed. Finally, after straightening, cutting, heat treatment, surface treatment, and performance testing, the finished nickel titanium cold-rolled tube is produced.

3、 Size specifications:

Wuge nickel titanium alloy material provides nickel titanium cold-rolled pipes, such as nickel titanium alloy ultra-thin wall pipes, with an outer diameter between 0.5-1.0mm, an outer diameter tolerance of ± 0.002mm, a wall thickness between 0.08-0.1mm, and an inner diameter tolerance of ± 0.002mm. The nickel titanium alloy seamless pipes provided have an outer diameter between 0.8-16.0mm, an outer diameter tolerance of ± 0.002mm, a wall thickness between 0.25-2mm, and an inner diameter tolerance of ± 0.005-0.03mm, and the specifications support customization.
