Aerospace-grade tensile strength up to 1000 PSI ensures durability, while its polished black oxide finish offers a sleek, low-friction surface. Pre-trained straight and fully customizable through heat treatment, this wire is perfect for educators, engineers, and innovators seeking reliable, flexible shape memory alloy solutions. ## Description 5 feet (1.5 meters) of 1mm diameter Nitinol SMA (shape memory alloy) wire. One of our favorites due to a comfortable warm, not-too-hot transition phase. This wire will become rigid and return to straight when exposed to temperatures above 40 C (hot water, lighter, heat gun, etc). Yes - it comes pre-trained STRAIGHT from the factory which is how you want it. You can re-train it if you want by heating it (500 C for 45 minutes) in the new desired shape. The wire has a lustrous titanium color (dark grey) with a bluish oxide tint on its surface. When freshly cut, the inner core is nickel white. Nitinol is very abrasion resistant and has self-healing properties, so the wire is quite hard to cut and kink. It feels very smooth and shiny to the touch. It does not require any special handling or protections from oxidation or moisture, and is non-toxic. Do not over heat it, as that will damage the property. If you are using electricity instead of hot water to activate it be sure to use a current limiting circuit. Review: Great for educational purposes - Used these for a phase transitions lab and they worked perfectly. The low temp transition worked great for K-12 students. Because it’s shape set straight and to have enough for each student, we cut into ~2” pieces with a wire cutter. Will definitely buy again. Review: True to form and function - I bought this as a science lesson for my child. The material comes wound in circle but the shape memory is straight. If you run it under warm water it will become a straight piece of wire :) So cool. I can't wait to create set a new shape memory at 1000°F. ## Features - Trained straight - the wire is very soft and pliable at room temperatures, and becomes stiff and straightens out at a very low heat point of 40C (about 100F), making it suitable for demonstrations without getting burned. - 1.0 mm (0.04") diameter is very thick, this wire can hold or pull many pounds of weight and it is virtually unbreakable. - Wire can be trained to take on a different shape by heat treating it at 500C and quenching in water. - Thick, strong & smooth - black oxide finish is shiny and low friction, with a mysterious sheen. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HP55XY0 | | Best Sellers Rank | #64,701 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Nitinol Wire | | Brand | Nexmetal | | Brand Name | Nexmetal | | Color | dark grey | | Customer Reviews | 4.4 out of 5 stars 129 Reviews | | Finish Type | Polished | | Gauge | 18.0 | | Grade Rating | Aerospace | | Item Diameter | 1 Millimeters | | Item Form | Coil | | Item Shape | Wire | | Item Thickness | 1 Millimeters | | Item Weight | 0.02 Pounds | | Material | Nitinol | | Model Number | niti-1.0-40 | | Number of Items | 1 | | Part Number | niti-1.0-40 | | Recommended Uses For Product | Scientific demonstrations, educational purposes, strong and flexible wire for various applications | | Tensile Strength | 1000 Pounds Per Square Inch | | UPC | 647732872200 | | Unit Count | 1 Count | ## Product Details - **Brand:** Nexmetal - **Color:** dark grey - **Finish Type:** Polished - **Item Weight:** 0.02 Pounds - **Material:** Nitinol ## Images ![5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) - Image 1](https://m.media-amazon.com/images/I/91xBB88+AQL.jpg) ![5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) - Image 2](https://m.media-amazon.com/images/I/A1Uf-QrGYvL.jpg) ![5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) - Image 3](https://m.media-amazon.com/images/I/313d0IK6bBL.jpg) ![5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) - Image 4](https://m.media-amazon.com/images/I/91nSjfsooLL.jpg) ![5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) - Image 5](https://m.media-amazon.com/images/I/91HFr22XSYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for educational purposes *by L***Y on June 19, 2024* Used these for a phase transitions lab and they worked perfectly.
