Spring-Back Multipurpose 304 Stainless Steel Wire
This wire bounces back after bending. Often used to construct springs and wire rope, 304 stainless steel is a good all-around choice for a wide range of applications.
PTFE-coated wire has a slippery surface, so it’s especially useful as a fish wire when navigating through confined spaces.

Hardened Undersized High-Speed M2 Tool Steel Rods

- Yield Strength: Not Rated
- Hardness: Rockwell C60 (Very Hard)
These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Platinum Wire

- Hardness: Rockwell B97 (Medium)
99.95% pure, this platinum wire is used for applications that require a soft material that resists corrosion and oxidation and has a high melting point. This wire allows heat and electricity to pass and resists oxide buildup, making it ideal for thermocouple probes, which require accurate readings even at high temperatures. Soft enough to create a good seal between two flanges, it's also used to make high-vacuum O-rings. Platinum's softness means it won't damage the flanges, so they can be used again. The high melting point of this wire makes it a better choice for sealing heated flanges than other materials such as gold.
