C17510 Beryllium Copper
CDA 17510, CA17510, RWMA CLASS 3, ASTM B441, HT, TH04, ASTM B534 

Typical for rod in HT temper

*Hardness conversions are approximate

**Test values are nominal approximations and depend on specimen size and orientation

The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable ASTM specification references.

​

C17510 Beryllium Copper RWMA Class 3 has high thermal conductivity combined with good hardness and high-temperature strength. This alloy is being chosen with increasing frequency for applications requiring a combination of high electrical conductivity and mechanical strength, and for applications requiring wear and corrosion resistance. Alloy C17510 Class III beryllium copper is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings. Class III alloy (having higher strength than class II), is recommended for highly stressed welder structural current carrying members and heavy-duty offset electrode holders. Class III alloy is generally recommended for spot welding and seam welding wheels having high electrical resistance, such as stainless steels. C17510 Beryllium Copper conforms to specifications ASTM B441 (ROD), ASTM B534 (PLATE) , RWMA Class III

What's Driving
Metal Prices

Factors creating the on-going surge in copper prices and base metal prices.

The U.S. imposed a 50% Section 232 tariff on the copper content of semi-finished and derivative copper products, effective August 1, 2025. These tariffs aim to bolster domestic production but create complexities for businesses in pricing, sourcing, and compliance, affecting global copper markets. 

In addition copper costs are soaring due to massive demand from the energy transition (EVs, renewables, grid) and AI data centers colliding with slow mine supply growth, production disruptions (labor, technical issues), aging mines, and government policies like tariffs, creating a structural supply deficit. 

Tin prices jumped to a record level due to a severe, ongoing global supply squeeze from mine disruptions (DRC, Myanmar, Indonesia) and increasing demand driven by its critical role in electronics (solder), green energy tech, and packaging, creating a significant market deficit and attracting speculative investment. Supply chain issues, including export permit delays and political instability in key producing regions, combined with growing recognition of tin's necessity for the energy transition, fueled a rally to multi-year highs in late 2025 and early 2026. 

Nickel prices are rising due to anticipated supply cuts from major producer Indonesia, tighter quotas, increased demand from stainless steel and EV battery sectors (despite some LFP shifts), speculative buying, and broader market strength in metals, with investors reacting to policy signals and potential disruptions.
