Nickel titanium is a very strong and durable metal alloy. It is also extremely easy to clean, corrosion resistant and antibacterial, which makes it ideal for camp cooking or outdoor adventures.
A nickel titanium spoon has a hardness of about 40 to 62 HRC and is free from pinholes or voids, which provides a smooth surface for use as a spork. It also has a nice comfortable grip and is lightweight.
Invented in the 1960s, nickel titanium is an engineering alloy that is used in a variety of applications. One of the most common uses is for orthodontics. The alloy is very useful for wires and brackets that connect the teeth, as well as for sure smile orthodontic braces.
The material is also used in various medical devices including stents, otoscopes, and dental implants because it is biocompatible and does not leach harmful chemicals into the body. It can withstand extreme cold and high temperatures.
Nitinol has two unique properties that are called the shape memory effect and superelasticity (also known as pseudoelasticity). It can deform 10 to 30 times more than ordinary metals, but it will return to its original, undeformed shape after removing an external load.
A method for manufacturing an article from a nickel-titanium composition comprises disposing a powdered nickel-titanium composition in a mold, sintering the powdered composition to produce a sintered preform, compacting the preform, machining the preform to form an article and further heat treating and quenching the article.
