This wire is thin, strong, and takes a lot of current - actually glowed a bright orange when the dial was set too high and wasnt damaged at all. ## Features - Hot wire styrofoam cutting - foam cutter - expanded polystyrene cutting - high strength Rene 41 alloy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DQT9VCY | | Best Sellers Rank | 792,712 in DIY & Tools ( See Top 100 in DIY & Tools ) 858 in Wire Cutters (DIY & Tools) | | Brand | AOKUP | | Colour | Silver | | Customer Reviews | 5.0 out of 5 stars 3 Reviews | | Included Components | Cutting Wire | | Included components | Cutting Wire | | Is Electric | No | | Manufacturer | General Electric | | Material | Metal | | Part Number | A | | Power source | Corded Electric | | Special Features | Durable | | Special feature | Durable | | UPC | 669014245823 | | Unit Count | 1.0 count | ## Product Details - **Brand:** ekecel - **Power source:** Corded Electric - **Colour:** Silver - **Included components:** Cutting Wire - **Special feature:** Durable ## Images ![Rene 41 hot Cutting Wire - styrofoam Cutter 0.4mm Diameter (2mtrs) - Image 1](https://m.media-amazon.com/images/I/71fuNA1qo2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ very strong, thin, and doesnt distort *by M***Y on 3 February 2019* I bought the wire to replace the rather poor quality wire that came with the Proxxon foam cutter, which was thicker and easily distorted no matter how tight it was fitted to the cutter.
