The expansion of global vehicle fleets and surging urban infrastructure development are directly contributing to elevated braze alloy consumption.

RESTRAINT

High material costs and volatile raw material pricing

The braze alloys market faces significant restraint due to fluctuating raw material costs. In 2023, silver prices averaged $23 per troy ounce, causing volatility in silver-based braze alloy pricing. Gold-based alloys, averaging $1,950 per troy ounce, presented even higher procurement costs. These fluctuations forced OEMs to reduce reliance on precious metals, substituting with alternative alloys where feasible. Additionally, copper prices fluctuated between $8,200 and $8,900 per metric ton in 2023, impacting cost structures across copper-based brazing operations. Such volatility restricts consistent pricing and complicates long-term contract negotiations for manufacturers.
