Thick walled 5/16" brass tubing supplier

[Deering Knives]

Currently using 5/16" brass tubing for lanyards. It's the thin walled stuff .014" wall thickness. I'm looking for a supplier, (preferably somewhere I can order other knife making supplies from) that regularly has the thick walled 5/16" brass tubing. Thanks in advanced for all the help!

Quick Google search has Speedy Metals with a .032" wall.
More than twice the thickness.
