英国采购需求：粉末加工、钣金、金属零件、钣金加工、金属加工、硅锰合金

I am looking to source pre-alloyed iron-based powders for the production of pinion gears. Specifically, I need formulations that include combinations of iron with elements such as copper and carbon, as well as nickel and molybdenum. These materials are critical for ensuring the durability and performance of the gear components. Could you please provide detailed information on the available grades, specifications, and pricing for these powders? Additionally, I would appreciate any insights into bulk purchase options and lead times for delivery. Looking forward to your prompt response.
