17-0907 v2.1/Bull Street Terraces/Tapware & Door Hardware - Stainless Steel or Unfinished Brass

QUESTION

We have been looking into materials and finishes for door hardware and tapware for our project in regional Victoria, Australia.

Is stainless steel or raw / unfinished brass considered preferrable ?

I understand the process of stainless steel contains chromium which is a read list material, however brass used for available door hardware contains lead. I know that some lead is allowed in door hardware (Specifica Exceptions - I10-E8 1/2009 Door Hardware), however is there any guidance on using stainless steel or un finished brass.

We have not been able to source fittings in lead-free or low-lead grade brass alloy.

ANSWER

Chromium is allowed in alloys and other building products as long as it is not in a hexavalent state. Chromium used for stainless steel alloys is typically in a zero valence state unless the product is chrome plated. Ingredients should be recorded down to a CAS Registry Number level. If the selectedmaterialhas a CAS Registry Number, it does not need to be broken down further into individual ingredients.

Because brass often contains lead, stainless steel is preferable.
