For what it's worth:
can you name a Chinese manufacturer of 1/4w carbon film resistors that uses copper wire for leads instead of plated steel?
One Chinese manufacturer known for producing 1/4W carbon film resistors with copper wire leads instead of plated steel is Xicon. Xicon is a reputable brand that often uses high-quality materials, including copper leads, for their resistors. However, it's always a good idea to verify the specifications with the supplier or distributor, as product details can vary.
Another option is Yageo, a Taiwanese company with significant manufacturing presence in China. They produce a wide range of resistors, and some of their carbon film resistors may feature copper leads. Again, confirming the specific product details is recommended.
If you're looking for a specific Chinese brand, Vishay Precision Group (which has operations in China) or Tyohm (a subsidiary of Yageo) might also be worth exploring. Always check datasheets or contact the manufacturer directly to ensure the leads are copper and not plated steel.
