Miscellaneous Grade Metal Alloys

Carbon Steel Alloys

Alloy 1010. Carbon Steel Alloy 1010 is a general purpose, low carbon steel with good weldability and forming. It is often used for general structural and automotive bodies, machinery stands, exhaust tubes, handles, hand rails, display stands, conveyor rollers, cold headed fasteners and bolts. Carbon Steel Alloy 1010 is a relatively low strength steel but can be quenched and tempered for increased strength.

Alloy 1018. Carbon Steel Alloy 1018 is a low carbon steel with good hardening properties. This alloy is easily formed, machined, brazed, welded and fabricated. Common applications for Carbon Steel Alloy 1018 include high volume screw machine parts, shafts, spindles, pins, rods, sprocket assemblies and a variety of component parts.

Thermocouple Alloys

Alumel. This magnetic wire alloy contains 94% nickel, 2% aluminum, 3% chromium and 1% silicon. Alumel has specific electrical resistance and is most commonly used in the production of type K thermocouples (with chromel), thermocouple extension wires and compensating cables.

Chromel. This alloy, sometimes called Chromel A, is made of 90% nickel and 10% chromium. Chromel is widely used to make positive conductors of ANSI Type E (with constantan) and K (with alumel) thermocouples, as well as heating devices. Resistant to corrosion and heat, Chromel can be used up to 1100°C in oxidizing atmospheres.

Constantan. Also known as Eureka, constantan consists of 55% copper and 45% nickel. It has the best overall combination of properties required for main strain gauge applications. Constantan's high resistivity to strain level and temperature, good fatigue life and high elongation capability make it the most widely used strain gauge alloy. Common applications include electrical resistors, shunts and type E thermocouples (with chromel).
