Wires and rods are used as electrodes, heating elements, thermocouples, evaporation sources and machining stock. This sub-category supplies them in pure metals and selected alloys. Listings include Platinum-rhodium alloy wire (Pt-30%Rh and Pt-6%Rh) for type B thermocouples, Aluminium wire from 0.025 mm to 2.0 mm diameter at up to 99.999%, annealed aluminium wire at 99%+ and Aluminium rod 6.35 mm at 99.95%.

Buyers specify diameter, length, temper and purity. Thermocouple wire must match an alloy composition closely so that its voltage output follows the standard tables. Ultra-fine wires are used in bonding and sensors, while thicker rods suit target making and machining. Tubes are selected by outer and inner diameter and wall thickness.

Wires are supplied on spools or in coils, rods and tubes in straight lengths, packed to prevent kinking and scratching. Each order ships with a COA. Precious metal wires are priced against current metal markets, so request a fresh quotation for each order.

Metal Wires, Rods & Tubes: questions buyers ask

What is type B thermocouple wire?

A type B thermocouple pairs platinum with 30% rhodium against platinum with 6% rhodium. It measures temperatures up to about 1,700 °C and is used in glass, steel and ceramic furnaces. The wire composition must be precise so the output voltage matches standard reference tables.

How is wire purity checked?

Purity is normally measured by spectroscopic methods such as ICP-OES, ICP-MS or glow discharge mass spectrometry on a sample of the lot. The COA lists the main impurities and the total purity on a metals basis. For electronics or vacuum use, also ask about gas content and surface cleanliness.

Can wires be cut to specific lengths?

Yes. Many wires and rods can be supplied cut to length, and some can be straightened or annealed after cutting. Send the diameter, length, quantity and any tolerance on length. Precious metal wires are often sold by weight, so we quote the metal value plus fabrication.
