Are weld repairs permissible on Class 1 and Class 2 nickel aluminium bronze forgings produced to Def Stan 02-833?

No, the rectification of defects by welding is not permitted on Class 1 and Class 2 (high integrity) forgings.

A 3% leaded brass tube, used to make an electrical fitting, cracked on crimping. Why?

Lead reduces the ductility of brass so use a tube with 1% lead.

A brass water fitting in dezincification resistant brass has been brazed. Should it be re-heat treated?

Yes, heat to 500 to 525oC, hold for two hours and slow cool, to ensure an all alpha structure.

A drawing refers to a material as B16. What is this?

B16 is an ASTM specification for free cutting brass rod and bar.

A drawing specifies TUNGUM for a pipe. What is TUNGUM?

TUNGUM is a trade name for aluminium-nickel-silicon-brass. CW700R (CZ127).
