鎳鋁青銅

鎳鋁青銅是以銅為基礎(chǔ)的合金;

• Aluminium (Al)
• Iron (Fe)
• Nickel (Ni)
• Manganese

這些材料也被稱為 Aluminium Bronze 或是 NAB

耐腐蝕性

• Good for sea water service
• Especially good for pitting corrosion, stress corrosion and corrosion fatigue
• Good fouling resistance

其他用途 & 評論

• 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

注意事項(xiàng)

• 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)
