Precision Machined Boron Nitride (BN) Components
Custom machining of Hot-Pressed Boron Nitride (Solid/Machinable Grade). Outstanding thermal shock resistance, zero wetness to molten metals, and clean self-lubricating properties.
Strategic Manufacturing Advantage
We machine complex, thin-walled Boron Nitride structural components down to 0.2 mm with tight tolerances, completely avoiding material delamination or micro-fracturing in vacuum fixture designs.
Key Material Properties
Quantitative engineering data for design validation and material selection
Why Choose Boron Nitride?
Hot-Pressed BN offers unique properties unmatched by other ceramics:
- Easy Machinability: Mohs hardness 1-2 allows complex geometries to be machined using standard carbide tooling, enabling rapid prototyping and cost-effective custom fixtures.
- Zero Wetness to Molten Metals: Non-stick surface prevents adhesion of molten aluminum, copper, gold, and other non-ferrous metals, critical for crucible liners and casting applications.
- Self-Lubricating: Layered crystal structure provides dry lubrication similar to graphite, but with superior oxidation resistance and dielectric properties.

Precision Machining Capabilities for BN
Complex geometry machining with easy machinability and rapid turnaround
Complex Geometry Machining
Standard carbide tooling enables intricate features, deep pockets, thin walls (down to 0.2 mm), and complex contours without specialized diamond tooling.
Rapid Prototyping Turnaround
Easy machinability allows fast iteration cycles. Prototype components can be delivered in 3-5 days for design validation and testing.
Tight Tolerance Machining
Despite softness, BN can be machined to ±0.02 mm tolerances for critical dimensions, enabling precision fixtures and insulators.
Thread Milling & Tapping
Internal and external threads can be directly machined into BN components, eliminating need for metal inserts in many applications.
Large-Format Fabrication
Machining of large BN plates and blocks (up to 400mm x 400mm) for vacuum furnace linings and thermal insulation systems.
Clean Room Compatible
BN produces minimal dust during machining and operation, suitable for semiconductor cleanroom environments with proper handling protocols.
