Here are a couple of links that may help you figure out what you are looking at .... or not, may even further confuse you, but it is information anyway!

Definitions of H59 & H62 Brass, which seems to be a Chinese material designation system based on approximate percentage of copper:

Here are some more common "Western" charts and definitions of Brass material specifications:

Title: Types of brass
Post by: Weedensteam on April 14, 2024, 01:21:08 pm

I have been purchasing my brass stock locally, my supplier suggested using C360 for what I am doing and I am happy with it.
Looking online most of the stock seems to be labelled H59 or H62 and is supplied offshore, I have tried to find how those definitions compare to the C360 I am using but there isn't any info I can find. Can anyone enlighten me?
