How Much Does a Scrap Transformer Weigh and How Is It Valued?

Understanding Transformer Scrap Value

When scrapping a transformer, the outer steel casing (the shell) is low-value ferrous scrap. The real money is inside. A typical oil-filled transformer contains about 25% to 30% core material (copper or aluminum) by weight. If you have a 1,000-pound copper-wound transformer, you might have 250 pounds of highly valuable copper inside.

However, extracting that copper requires specialized equipment, draining the oil (which must be handled according to EPA regulations), and separating the steel core from the windings. Because of this, most businesses sell transformers as "whole units" to specialized buyers who have the facilities to safely process them.

Why Sell to Industrial Specialists

Local scrap yards often pay bottom dollar for whole transformers because they don't process them in-house—they just resell them to larger processors. At Scrap Metal Buyers, we buy transformers directly for processing or, in many cases, for reconditioning and resale. If your transformer is late-model or still functional, it may be worth 2x to 5x its scrap value on the surplus market.

Before you send a heavy transformer to the shredder, call us. We handle the heavy lifting, freight, and environmental compliance, and we pay top dollar based on real-time copper markets.
