Copper Shims Supplier in India
If you’ve ever tried to bed down a busbar connection or level a heat exchanger baffle, you already know why copper shows up so often on the shim list — nothing else moves heat and current the way it does. That’s really the whole reason Kalpataru Piping Solution keeps a running stock of copper. We’re a Mumbai-based copper shims supplier and exporter, and our shims are cut from certified C10200 and C11000 electrolytic-grade copper as well as Beryllium Copper, in sheets, coils, foils and ready-to-fit precut pieces. If your job needs a burr-free, exact-thickness shim rather than a slab of coil stock you’ll cut yourself, that’s what we do all day. We also stock the neighbouring grades — brass shims for lighter electrical work, ready-cut precut shims for machinery alignment, and dedicated alignment shims — so if copper turns out not to be the right call for your application, we can point you to what is. Below you’ll find our copper shim specifications, standard sizes, weight chart, grades and pricing pointers, written the way we’d explain it over a phone call rather than a marketing brochure.

What is Copper shim?
Copper shim stock does one job better than almost any other metal: it moves heat and electrical current with very little resistance, and it does that while staying soft enough to conform to slightly uneven surfaces. We supply copper shims as flat sheets, coils, foils, blanks and precut pieces, in electrolytic tough-pitch grades (C10200, C11000) and in Beryllium Copper (C17200) where strength and non-sparking behaviour matter more than raw conductivity. Cutting is done by slitting, CNC laser, stamping or waterjet depending on thickness and the finish you need.

FAQ’s About Copper Shims
C10200 (OFHC) is oxygen-free copper with slightly higher conductivity and purity, typically chosen for electronics and vacuum-sensitive work. C11000 (ETP) is the standard electrolytic tough-pitch grade used for most general electrical and shimming applications, and it costs less.
Yes, within limits. Copper resists heat well and retains its shape and strength up to roughly 200°C in continuous service, and it can handle brief excursions higher than that. For sustained high-temperature duty above that range, nickel alloys like Inconel are usually a better fit.
Beryllium Copper is alloyed and heat-treated to achieve strength levels closer to spring steel while staying non-magnetic and spark-free — that processing, plus the cost of the beryllium alloying element itself, is what pushes the price above plain copper.
From roughly 0.05 mm foil up to 8 mm plate, in coil, sheet, strip, blank, ring or precut form. If you need a size outside our standard range, tell us the application and we’ll quote a custom run.
Yes. Share a DXF, DWG or PDF drawing with your required grade, thickness and quantity, and we’ll cut it using laser, stamping or waterjet depending on tolerance and batch size.
