One other nice perk about Bronze is that it's easy to machine (as compared to stainless), and or have custom castings & such made from it. Port Townsend Foundry in Washington
- Nice folks.
That said, I'd vote for G10. NOTE: Before you buy some, check on it's rated mechanical properties. As the fiber type(s) in it, & fiber to resin ratios vary wildly. For instance, some is made with Carbon Fiber (and is autoclaved HEAVILY), giving it a strength on par with/in excess of that of Aluminum
. While other brands are barely a tenth of that strength.
Here's a good place to look/resource - www.Matweb.com
It lists all kinds of mechanical properties on things you've never even heard of, in addition to sources of who supplies what.
