镍铝青铜

镍铝青铜是以铜为基础的合金;

• Aluminium (Al)

• Iron (Fe)

• Nickel (Ni)

• Manganese

这些材料也被称为 Aluminium Bronze 或是 NAB

• EN1982: CC333G

其它

• ASTM B148 UNS C95500 (10/4/2)

• ASTM B148 UNS C95400 (11/4)

• ASTM B148: 10 alloys in total

典型物性

• Tensile 580-640 N/mm2

• Yield 240-250 N/mm2

• Elongation 13- 15%

• Hardness HB140

• Density 7.6 g/cm3

• Good castability, reasonable bearing material, easy machining, high strength

• P/T Ratings Shipham SPT01 19 bar for class 150

• EN1759-3:2003 15.5 bar class 150

耐腐蚀性

• Good for sea water service

• Especially good for pitting corrosion, stress corrosion and corrosion fatigue

• Good fouling resistance

其他用途 & 评论

• Variety of wrought specifications available, good for trim material

• Low magnetic permeability

• Non-sparking; can be used for oxygen service

• Reasonable thermal and electrical conductivity

• Good Castabilty with suitable design

• Weldable

• Can be heat treated to improve sea water corrosion properties

注意事项

• Low modulus of elasticity, but good yield stress

• - Raised face flanges non-standard

• High temperature use

• - Observe pressure ratings at higher temperatures

• Should not be used in polluted / H2S containing sea water (in common with 316 Stainless)
