High Materials Costs Squeeze Connector Manufacturers

The buildout of AI infrastructure and expanding electrification are increasing demand for base metals. Now, unprecedented price increases in the gold, silver, and copper markets are putting pressure on connector manufacturers in a direct challenge to cost structures, pricing strategies, and supply chain resilience.

Connector and cable manufacturers are navigating a challenging raw materials environment that is raising costs at every step of the supply chain. By early 2026, gold prices passed $5,000 per ounce, silver prices passed $100 an ounce, and copper reached $13,300 per ton on the London Metal Exchange. Although prices have since fallen from these historical highs, these prices represent new demands for precious and base metals driven by AI infrastructure buildout and electrification. For an industry whose cost base is built on these materials, the implications are profound.

Global AI infrastructure investment exceeded $500 billion in 2025, with Goldman Sachs projecting a 165% increase in data center power demand by 2030 — all of it requiring copper-intensive wiring, connectors, and bus bars. Electric vehicles, which use 80–100 kg of copper each versus roughly 25 kg in internal combustion vehicles, are expected to consume 5.6 million metric tons of copper annually by 2040, up from 2.7 million in 2025. Grid modernization investments are adding further pressure: China alone has announced a $300 billion four-year grid expansion program.

On the supply side, copper is experiencing severe supply constraints. A series of natural disasters and other disruptions at major mines contributed to a global copper market deficit projected at 150,000 to 330,000 metric tons in 2026, after recent surpluses. Silver shortfall for 2025 is estimated at 95 to 230 million ounces; roughly 75% of silver is produced as a byproduct of copper, lead, and zinc mining, meaning its supply is tied to supply and pricing of other materials. Additionally, China placed silver under export licensing controls beginning January 1, 2026 — similar to its existing rare earth regime — introducing new geopolitical dimensions. Silver prices directly affect multi-layer ceramic capacitors (MLCCs), conductive pastes, and wire bonding in semiconductor packaging — all elements of the integrated circuit supply chains that connector manufacturers and their customers depend on.

Connector industry response

This metals volatility has become a major concern to the connector industry. In Hirose Electric’s Q4 FY2025 financial results briefing, President Shin Kamagata acknowledged gold as a risk factor in the company’s financial forecast. The company reported that rising material costs contributed to a 5% year-over-year decline in operating profit despite an 8.4% sales increase for the nine-month cumulative period.

The company plans company-wide price increases focused on older products with thick gold plating, particularly in the industrial machinery market. Some customers will transition to gold market-linked pricing contracts, said Kamagata in the company’s second quarter financial results briefing. Also, Hirose’s engineering teams are evaluating reduced gold content and alternative materials for new product generations. “We have been researching and developing gold-saving production and alternative metals for a long time, so we are thinking of accelerating this year. It is difficult to assume that the price of gold will return to normal suddenly, so we are currently planning to reduce the amount of gold or to introduce new materials other than gold.”

Amphenol CEO R. Adam Norwitt attributed the company’s resilience in part to its decentralized operating model. During the company’s Q4 2025 earnings call, analysts asked how Amphenol manages supply chain constraints and higher metals prices, Norwitt emphasized the company’s unique operating culture, which empowers general managers to address challenges locally. Amphenol’s huge scale, and product and market diversification, enables the company to better manage metals price volatility has been absorbed without material margin degradation. However, the company acknowledges potential “risks associated with our inability to obtain certain raw materials and components, as well as the increasing cost of certain of the company’s raw materials and components.”

TTI Inc. closely watches the materials supply chain and the various forces that ultimately impact component pricing. High copper and gold prices have triggered company-wide pricing increases across components. Connector manufacturers with gold-intensive product lines are pursuing market-linked pricing contracts, an approach that shifts price risk to customers. Circuit board manufacturers have increased prices up to 30% across all thicknesses. Passive component suppliers including capacitor, inductor, and ferrite bead manufacturers have implemented single- to double-digit price increases.

In December 2025, Molex and TE Connectivity announced price increases to take effect in January 2026, citing persistent inflationary conditions and rising input costs, including higher metal prices. In TE’s Q1 FY2026 earnings call, CFO Heath Mitts said, “We are seeing pressure — inflationary pressure on the metals specifically. That category is our largest purchase category.”

Despite the metals pressure, Heath said TE has improved its agility or nimbleness to pass on pricing on these inflationary measures more quickly. TE posted record adjusted operating margins of 22.2% and record orders of $5.1 billion for Q1. Management said they do not expect metals inflation to affect their margin targets significantly.

Gold in high-reliability markets

Nowhere is gold more critical than in military and aerospace applications. MIL-spec connectors typically require thick gold plating — often in the range of 50 to 100 microinches or more — on contact surfaces to meet stringent reliability, corrosion resistance, and mating cycle requirements. Unlike commercial connectors where thin flash gold or alternative finishes may be acceptable, mil/aero standards specify plating requirements that cannot be changed without requalification.

This poses problems for defense contractors under long-term contracts that may have been established years earlier when gold was at much lower prices. Cost escalation clauses vary widely. This challenge is compounded by counterfeiting risks. The industry has seen cases where cost pressure drives the use of non-conforming materials or substitute finishes. Organizations like ECIA have long emphasized the importance of sourcing through authorized channels precisely because precious metal shortcuts in safety-critical applications pose catastrophic reliability risks. Higher gold prices underscore the importance of supply chain integrity in high-reliability markets.

Industry responses

ECIA has been tracking tariff policy developments, supply chain compliance, and market intelligence as the overlap of commodity price volatility, trade policy, and product demand creates a more complex operating environment. Chief Analyst Dale Ford has highlighted that inflation’s impact on material and labor costs has played an increasing role in industry dynamics, noting that while elevated prices may provide a temporary boost to revenue, they ultimately create headwinds for sustainable growth if they persist.

For the connector industry, the era of absorbing metals volatility quietly is giving way to dynamic pricing actions and new product strategies. Manufacturers are aligning cost structures with the new materials reality to sustain both profitability and customer relationships through what may be a prolonged period of elevated metal prices.
