Chromium Rod

    Chromium Rod: Defining High Temperature Performance and Purity Benchmark for Modern Industry

    Chromium rods are an indispensable structural core in the fields of alloy melting, high-energy physics experiments, and cutting-edge PVD coatings. With its extremely high hardness, superior corrosion resistance, and astonishing melting point of 1907 °C, the chrome rod is not only an added metal, but also a precision component that supports extreme stability.

    Basic performance: physical power against limits Because of its unique atomic structure, chromium rods have the reputation of "silver protector" in the material industry:

    Extreme oxidation resistance: Even at high temperature, the surface can quickly form a protective oxide layer to prevent further internal corrosion.

    High hardness and low wear: As a metal with extremely high Mohs hardness, chromium rods show extraordinary dimensional stability when subjected to mechanical scouring.

    Excellent thermal-electric characteristics: It has good conductivity and stable thermal coefficient, suitable for precision electrode applications.

2. Chemical composition and technical indicators (Ultra-High Purity)

    We adopt vacuum induction smelting and electrolytic refining technology to ensure that the impurity content reaches the lowest level in the industry.    

3. Lean process: from powder to dense crystal

    The birth of every chromium rod is the ultimate pursuit of the densification process:

    High pressure isostatic pressing (HIP): Eliminate microscopic pores inside the billet.

    High-temperature vacuum sintering: long-term cross-linking in the absence of oxygen. Precision forging and drawing:

    Refine the grain structure and significantly improve the tensile strength of chromium rods.

    Vacuum stress relief: Ensure that no fracture or bending occurs during subsequent machining.

4. Product specifications and basic information parameters

    Diameter range: 3.0 mm-300mm (supports non-standard customization)

    Length range (Length): 10 mm-1500 mm

    Straightness: ≤ 0.1 mm/m

    Dimensional tolerances: h7, h8, h9 or custom-made ± 0. 05 mm

    Hardness: HRC 25-35 (depending on working condition)

5. Surface treatment: craftsmanship achieves texture

    Ground: Eliminate machining marks and improve fit size.

    Polished surface: Mirror gloss, suitable for vacuum that requires extremely high outgassing rate.

    Turned surface: retains the primary color of the metal, suitable for use as a smelting additive.

6. Core advantage: Why do senior purchasers choose our chrome rods?

    Grain consistency: The optimized forging process ensures fine and uniform grains from the surface to the core, avoiding cracking during processing.

    Extremely low gas impurities: Strict control of gas elements greatly prolongs the service life of targets in PVD applications.

    Out-of-the-box: Standard ultrasonic non-destructive testing to ensure that there are no cracks or inclusions inside each bar.

7. Application field: driving the global high-tech industry chain

    Vacuum coating: As the core component of cylindrical sputtering targets, it is used to manufacture wear-resistant coatings.

    Special alloys: engine blades, high-temperature alloy steel important additive elements.

    Laboratory Research: High Temperature Corrosion Resistance Testing for Semiconductor and Nuclear Industries.

    Precision Instruments: Manufacture of sensor probes and structural rods for extreme operation.
