Beryllium Copper Square Plate Manufacturer, Supplier and Stockist

HOME → Hot Products → Beryllium Copper → Beryllium Copper Square Plate

A square plate cuts cleaner from stock than most people expect, and that is half the reason buyers ask for it by shape instead of just ordering a rectangle and trimming it down. A beryllium copper square plate is flat, square-cut beryllium copper stock, almost always UNS C17200, known on the shop floor as Alloy 25 or CuBe2, supplied to ASTM B194. You order it by side length and thickness rather than length and width, and it comes either annealed, ready to machine or form, or age-hardened, ready to use as is. Sachin Steel Centre in Mumbai stocks beryllium copper square plate with a mill test certificate on every lot, and we cut to your drawing where a standard size does not fit.

Frequently Asked Questions

What is a beryllium copper square plate?

Beryllium Copper Square Plate is a C17200, Alloy 25, or CuBe2 square blank supplied by side length and thickness for machining and age hardening.

What sizes and thicknesses of square plate are available?

Beryllium copper square plate size depends on stock and cutting capability. Specify the required side length and thickness for confirmation of available C17200 square plate dimensions.

Can a beryllium copper plate be cut to a square to my size?

Yes. Beryllium copper plate cut to size can be supplied by specifying side length, thickness, tolerance, and quantity. Cutting should use suitable dust extraction.

What is the difference between C17200, Alloy 25, and CuBe2 square plate?

C17200 square plate, Alloy 25 square plate, and CuBe2 square plate identify the same beryllium copper alloy under different designation systems.

Can a square plate be machined before it is hardened?

Yes. A BeCu square plate is commonly machined in the annealed condition before age hardening. The exact heat-treatment cycle should follow the applicable material datasheet.

Which ASTM standard covers beryllium copper square plate?

ASTM B194 covers C17200 plate, sheet, strip, and rolled bar. ASTM B248 provides general requirements and dimensional tolerances for copper beryllium products.

What is the difference between a square plate and a rectangular plate or sheet?

A square beryllium copper plate has equal sides, while a rectangular plate has unequal sides. 'Sheet' generally refers to thinner material, depending on the applicable specification.

Is a beryllium copper square plate safe to machine?

Machining a beryllium square plate can generate hazardous dust or fumes. Use suitable extraction, protective equipment, and workplace controls according to applicable safety requirements.

What is the price of beryllium copper square plate per kg?

Beryllium copper square plate price depends on alloy, temper, dimensions, quantity, cutting, and market conditions. Contact a manufacturer, supplier, stockist, or exporter for a quotation.
