    Copper Wire

    Image of Product. Front orientation. Copper. Copper Wire.
    Highly conductive and soft enough to form, copper wire is the go-to for electrical jobs. It's often used to power motors, create grounding, and wire control panels, lights, and transformers.
    Tin-Coated 110 Copper—More corrosion resistant and easier to solder than uncoated 110 copper wire.
    High-Temperature Nickel-Clad 101 Copper—Stays corrosion resistant and conductive in temperatures as hot as 1200° F.

    Ultra-High-Temperature Molybdenum Wire

    Image of Product. Front orientation. Molybdenum. Ultra-High-Temperature Molybdenum Wire, Spool.

    Spool

    Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments. It resists oxidation and won’t corrode. Molybdenum is better at conducting heat and electricity than tantalum and platinum, which also have high melting points. It is not, however, as corrosion resistant.

    Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods

    Image of Product. Front orientation. Steel. Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods.
    These rods, also known as drill blanks, have an undersized diameter for machining your own 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.
