Since November, international tin prices have not seen a unilateral sharp rise, yet the all-time high of RMB 285,800 per ton (as of November 10) has sounded the cost alarm for downstream industries.

Lagging resumption of production at mines in Wa State, Myanmar, Indonesia's ongoing crackdown on illegal mining, and geopolitical conflicts in Africa have collectively constrained global tin ore supply. Meanwhile, steady demand from sectors such as semiconductors and new energy has provided solid support for the high prices.
For the sintered diamond tools industry, high tin prices are directly driving up matrix costs. As a key bonding metal, tin plays three irreplaceable roles: reducing sintering temperature, adjusting matrix toughness and hardness, and filling pores to enhance holding force. Its cost fluctuations directly impact product performance and profitability.
We advise enterprises to:
- Establish a flexible procurement mechanism – decisively increase inventory when prices are relatively low and build long-term strategic cooperation with core suppliers to stabilize supply;
- Launch formula optimization projects, accurately assess the minimum effective tin content, and actively explore cost-saving and efficiency-enhancing process routes.
-
The current trend of tin prices directly determines the cost curves and competitiveness of downstream enterprises. Proactively adjusting procurement strategies and accelerating technical optimization is an inevitable choice for enterprises to control costs and safeguard profits.
