Coating for caps for blood bottle: EN vs. Nickel-chrome plating

December 7, 2013

Q. Dear Sir,

We are manufacturing ALUMINIUM CAP - exclusively used for BLOOD BANK which is cap for BLOOD BOTTLE.

CAN ALUMININUM CAP COATING BE MADE ONLY BY "ELECTROLESS NICKEL COATING" OR MERELY NICKEL CHROME COATING? WHICH IS BEST ONE?

PLEASE REPLY.

A. Hi Mohan. Surely there are standards which dictate this construction, rather than it being left to people's whims to decide as they will? But electroless nickel will be more corrosion resistant than nickel-chrome plating.

Regards,
