The material is cold drawn to the desired size and heat treated by a continuous tempering method. A low temperature stress relief is required after processing. Wire is available is size ranges from 0.023" - 0.625". Learn More
Oil Tempered MB Spring Wire Class II - (25)
This is a general purpose, commercial quality, Class II tensile, spring steel wire to ASTM A 229. With a quality between hard drawn spring wire and music wire, moderately priced OTMB is excellent for springs without severe bends. The material is cold drawn to the desired size and heat treated by a continuous tempering method. A low temperature stress relief is required after processing. Wire is available in size ranges from 0.120" - 0.625". Learn More
Oil Tempered Chrome Silicon - Commercial Quality - (106)
This material is designed for springs that must withstand considerable shock and extreme heat. Chrome silicon can be used at temperatures up to 50°F higher than chrome vanadium. Recommendations for heat treatment: Immediately after coiling, the springs should be stress relieved at about 400°C (750°F) for 30 minutes. After shot peening, the springs should be stress relieved at about 250°C (480°F) for 30 minutes. Wire is available in size ranges from 0.018" - 0.625". Learn More
Oil Tempered Chrome Silicon - Valve Spring Quality - (56)
These materials are designed for springs that must withstand considerable shock and extreme heat. Chrome silicon can be used at temperatures up to 50°F higher than chrome vanadium. Valve spring quality chrome silicon has been eddy current tested to assure the finest possible surface in keeping with automotive industry requirements. Wire is available in size ranges from 0.0217" - 0.312". Valve quality Chrome Silicon conforms to ASTM-A-877. Learn More
Oil Tempered Chromium - Vanadium Wire Commercial Quality - (28)
Chromium-vanadium is the most popular alloy steel for springs that are required to withstand a large number of operating cycles. It is medium carbon steel with chromium and vanadium added to increase its hardness and tensile strength. The pre-tempered material is best for valve or gun springs. Springs can be used at extremely high stresses in applications where they will also be subject to extreme shock and impact loading. Learn More
Oil Tempered Chrome Vanadium - Valve Quality - (34)
These materials are designed for springs that must withstand considerable shock and extreme heat. Valve spring quality chrome vanadium has been eddy current tested to assure the finest possible surface in keeping with automotive industry requirements.

Type Corrostan Music Wire - (18)
Corrostan is an electro-galvanized, zinc coated music wire provided on reels and cores for long continuous production runs. Drawing after plating provides a zinc hard enough to withstand automatic coiling or mechanical forming operations without excessive peeling or flaking. Wire is available in size ranges from 0.017" - 0.068". Larger diameters can be special ordered up to .098". All Corrostan conforms to ASTM-A-228 & SAE-J-178. Learn More
Galvanized Low Carbon Wire - (51)
Galvanized low carbon wire is often referred to as galvanized basic wire offers various degrees of corrosion resistance according to the weight of coating applied. It can be offered in soft, medium and hard tensiles as well as class 1, 2 and 3 coating weights depending on the customer requirements. Learn More
Tinned Coated Music Wire - (18)
A commercial coating weight is standard but specific weights of coatings can be produced according to the customer requirements. Learn More
Zinc-Aluminum Music Wire - (52)
Zinc Aluminum coating is known in the industry by trade names Bezinal and Galfan as well as Alumar and Corzal coatings. It is traditionally a 95% zinc coating with the addition of 5% aluminum. Other coating concentrations can be for example 90% zinc and 10% aluminum. This product offers superior resistance to rust over just a hard drawn or regular galvanized product. Learn More
Bright Low Carbon Wire - (49)
The most widely used wire product in the world. It generally refers to wire with a carbon content of 0.25 max. It is easy to form into various wire products on four slide machines and CNC equipment. It is extensively used in concrete construction as a reinforcing product as well as wire forms for consumer items. Learn More
Preco "Z" Music Wire - Galvanized Music Wire - (67)
This coating can be applied to products such as high and low carbon wires including music wire, hard drawn MB and low carbon. Learn More
Preco "N" Music Wire
Preco "N" is a nickel coated music wire which offers superior consistency and reliability, due to drawing after nickel coating, for such applications as computer keyboard springs, camera springs, battery springs, and cordless telephone antennas. Preco "N" exhibits minimum discoloration during stress relieving because no rust proofing oils are needed. Wire is available in limited size ranges from 0.015" - 0.032" and is also available on application. Preco N conforms to ASTM-A-228 & SAE-J-178 Learn More
