In the "cold" state, these nitinol feathers can be easily deformed - If you expose them to a temperature of about 65 °C, they jump back into the stored spring shape - The shape that it then takes can be stored almost as desired. In this case, a spring - Return temperature approx. 65 °C, total length: 25 mm (including eyelets), spring diameter approx. 6 mm, number of coils 21, wire diameter 0.75 mm - Nitinol springs are not arbitrarily deformable. Please refer to the instructions for use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00XZSOZJG | | Batteries Required? | No | | Batteries included? | No | | Customer Reviews | 4.4 4.4 out of 5 stars (16) | | Date First Available | 26 Sept. 2015 | | Item Weight | 9 g | | Manufacturer | fuxus | | Manufacturer reference | 3300058-5 | | Number of Pieces | 1 | | Package Dimensions | 10.16 x 5.08 x 0.25 cm; 9 g | | Part Number | 3300058-5 | ## Images ![5 pieces Fuxus® Nitinol Memory Metal Springs Shape Memory Alloy Spring Memory Foam, Alloy 65 °C - Image 1](https://m.media-amazon.com/images/I/71YQ3IBITvL.jpg) ![5 pieces Fuxus® Nitinol Memory Metal Springs Shape Memory Alloy Spring Memory Foam, Alloy 65 °C - Image 2](https://m.media-amazon.com/images/I/71E-6qBqBvL.jpg) ![5 pieces Fuxus® Nitinol Memory Metal Springs Shape Memory Alloy Spring Memory Foam, Alloy 65 °C - Image 3](https://m.media-amazon.com/images/I/81Dko3LP3LL.jpg) ![5 pieces Fuxus® Nitinol Memory Metal Springs Shape Memory Alloy Spring Memory Foam, Alloy 65 °C - Image 4](https://m.media-amazon.com/images/I/71R2ySNapwL.jpg) ## Frequently Bought Together - Fuxus Nitinol Memory Metal Spring Shape Memory Alloy, 45C (113F) - 2-Way Nitinol Shape Memory Alloy Spring; 0.7mm9mm15-60mm; Af 60C Mf 30C - 5 Feet Nitinol Shape Memory Pre-trained Wire (1.0mm 40 C (18ga 104 F)) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/86400669-5-pieces-fuxus-nitinol-memory-metal-springs-shape-memory-alloy](https://www.desertcart.tn/products/86400669-5-pieces-fuxus-nitinol-memory-metal-springs-shape-memory-alloy) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-28*
