Nickel Plating Precision CNC Machined Invar Component Consistent Surface Finish

Precision CNC Machined Invar Component – Syris Manufacturing

Product Overview

This precision CNC-machined plate, produced by Syris, is manufactured from Invar alloy (Fe-Ni36) and finished with bead blasting followed by nickel plating. The part features a stepped mounting flange, a recessed central pocket, and a precision-bored multi-hole pattern, reflecting Syris's capability in machining low-expansion alloys to tight tolerances for high-stability applications.

Material & Finish

• Material: Invar Alloy — Selected for its exceptionally low coefficient of thermal expansion (CTE), Invar maintains dimensional stability across wide temperature ranges, making it ideal for precision optical, aerospace, and metrology applications.
• Bead Blasting — A uniform, fine-grain matte surface texture is achieved through bead blasting, removing machining marks and providing a consistent base for plating.
• Nickel Plating — An even nickel coating enhances corrosion resistance, surface hardness, and wear performance while preserving the underlying dimensional precision of the substrate.

Key Features

• Recessed Pocket Feature — A precisely milled rectangular recess with clean, sharp internal corners demonstrates tight-tolerance pocket machining.
• Multi-Hole Mounting Pattern — An array of precision-bored through-holes of varying diameters allows for flexible mounting and integration with mating assemblies.
• Stepped Profile Flange — Contoured edge geometry with notched corners supports precise alignment and space-efficient installation.
• Dimensional Stability — Low-CTE Invar substrate combined with CNC precision ensures the part holds critical tolerances under thermal cycling.
• Consistent Surface Finish — Bead-blasted and nickel-plated surface delivers a uniform, corrosion-resistant appearance suitable for precision instrument and OEM-visible use.

Applications

Well suited for precision optical mounts, aerospace and satellite structural components, metrology fixtures, semiconductor equipment, and other applications where thermal stability and dimensional accuracy under temperature variation are critical.

Manufacturing Capability

This component showcases Syris's expertise in machining specialty low-expansion alloys, combined with secondary surface treatment processes (bead blasting and nickel plating) to deliver functional, corrosion-resistant, dimensionally stable precision parts from prototype through production volumes.
