 Main Technological      Properties
 A heat treatable copper-nickel-phosphorous alloy.  Our B98 has  medium to high mechanical properties,  good electrical and thermal conductivity,  good cold formability and is suitable for welding. Our B98 is particularly resistant to fatigue stress and has excellent thermal stress relaxation properties.
 Some Typical Uses

 

Our B98 has various uses in the electronics industry. Springs, contacts, clips and other connecting items are made from strip. Rods and hollow rods are used as electrodes, jaws and contact rolls for welding purposes. B98 in strip form is a  good substitute for many low beryllium alloys such as CuCo2Be / CuCo1Ni1Be / CuNi2Be (UNS C17410...C17510).  Our B98, with the additional benefit of increased strength, can also be substituted for Cu-Fe-P alloys (UNS C19400...C19750).

Standards Remark: The mechanical properties mentioned in the EN 12163 standard are not correct.
Explanation  Ø =  Diameter of round rods (mm) Rm = Tensile strength
H = Outside diameter for hollow rods drawn without mandrel Rp0,2 = 0,2 yield strength
s = thickness for strips (mm)

Corrosion characteristics Resistance in different environments Rating
humid ammonia , chlorine very poor

 Our B98 has a high and positive standard potential of corrosion. Consequently, there is a risk of galvanic corrosion if it enters into contact with material of lower standard potential, such as steel containing less than 13% of chromium.
B98 is not sensitive to stress corrosion
