Stainless Steel Alloy Hidurel® 5
Hidurel® 5 is a solution annealed and precipitation treated copper-nickel-silicon alloy. Hidurel 5’s widespread usage in a large number of industries is due in part to its high electrical and thermal conductivity, along with its high mechanical strength. Other key features of Hidurel 5 include:
- Excellent bearing and anti-friction properties
 - No loss of impact strength down to -196°C
 - Easy to machine
 - Low magnetic permeability and spark resistance
 - Top ranked corrosion resistance for marine environments
 - Good marine fouling resistance
 
In order to be sold under the Hidurel 5 brand name, an alloy must consist of the following chemical properties:
- Cu Remainder
 - Ni 2.0-3.5%
 - Si 0.4-0.8%
 - Al 0.02% max
 - Fe 0.01% max
 - Total Impurities 0.30% max
 
Some of the industries that Hidurel 5 is prevalently used in include industries like aerospace, defense, automotive, general manufacturing and hydraulic and mechanical engineering.
At Continental Steel we are a distributor of Hidurel 5 in an array of different sizes and forms including bars and sections. As would be expected from Continental Steel, all of the Hidurel 5 we source meets a number of different industrial standards such as BS, BS2, DTD, CW, and UNS.
