Platinum Tube Description

Platinum Tube is made from high-purity platinum through rigorous processes, ensuring precise dimensions and flawlessly smooth surfaces. The inner diameter and wall thickness can be customized according to specific requirements. Its inert nature resists strong acids/alkalis, while maintaining structural integrity under extreme heat. It is widely applied in semiconductors, chemical catalysis, medical devices, and scientific research. Heeger Metal specializes in manufacturing high-purity platinum products with precision engineering, offering an extensive range of products including platinum capillary tube, platinum marker band, platinum iridium alloy tube, platinum iridium alloy capillary tube, platinum iridium alloy marker band, etc.

Platinum Tube Manufacturing Processes

After high-purity platinum is cold-rolled and pressed into sheets, it undergoes solid solution annealing. The material is then subjected to mechanical drawing, shaping, and polishing to produce platinum tubes. The detailed processes are as follows:

  • Raw Material Purification: High-purity platinum (typically ≥99.95%) is further refined via electrolysis or chemical methods to remove impurities.
  • Melting & Casting: The platinum is melted under high temperature in an inert gas atmosphere and cast into rods or billets.
  • Hot Working (Hot Rolling/Extrusion): The billet is heated to a malleable state and formed into a rough tube shape through rolling or extrusion.
  • Cold Working (Cold Drawing/Rolling): The tube is gradually drawn or rolled at room temperature, with intermediate annealing to relieve work hardening, achieving precise dimensions.
  • Annealing: Annealing in a controlled atmosphere or vacuum restores ductility and eliminates internal stresses.
  • Precision Finishing & Surface Treatment: Polishing and ultrasonic cleaning are applied to ensure a flawless surface, critical for high-purity applications (e.g., semiconductors or medical devices).
  • Quality Inspection: Spectrometry (composition check), dimensional measurement (micrometer/laser gauging), leak testing, and microstructure analysis (metallography) are conducted to verify compliance.

Platinum Tube Applications

  • Chemical Industry: Platinum tubes are widely used in chemical reactors, catalyst supports, fine chemicals synthesis, and high-temperature chemical processes due to their excellent corrosion resistance and thermal stability.
  • Medical Devices: Platinum’s biocompatibility makes it ideal for use in medical devices, implants (such as pacemakers and electrodes), and laboratory analysis equipment.
  • Electronics Industry: Platinum tubes are also used in high-precision electrical components and sensors, especially in high-temperature, high-pressure, and corrosive environments.
  • Aerospace: Due to its strong oxidation resistance and high-temperature tolerance, platinum is used in critical components of spacecraft and high-end aviation equipment.

Platinum Tube Packaging

Platinum Tube is carefully placed in wooden cases or cartons with additional soft materials to support and prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.

We carry a wide variety of platinum products in stock, and for these, there is generally no minimum order requirement. However, for custom orders, we typically set a minimum order value of $200. The lead time for stock items is usually 1-2 weeks, while custom orders usually take 3-4 weeks, depending on the specifics of the order.

DFARS (Defense Federal Acquisition Regulation Supplement) compliance is primarily concerned with the sourcing of materials for defense-related applications in the United States. According to DFARS, certain materials used in defense must be sourced from the United States or qualifying countries.

If you have specific platinum materials that are subject to DFARS, please let us know in advance and we will confirm.

At Heeger Metal, we take this responsibility seriously. We adhere to all applicable laws and regulations, including Section 1502 of the Dodd-Frank Act. Our company operates with a strict code of ethics and is committed to only partnering with suppliers who share our dedication to responsible sourcing. We support the initiatives and programs aimed at promoting “conflict-free” supply chains and work diligently to ensure that our products meet these standards.

Platinum tube are widely used in semiconductors, chemical catalysis, medical devices, high-temperature experiments due to their corrosion resistance, and thermal stability, and conductivity.

Platinum tubes withstand up to 1600℃ long-term (1800℃ short-term) in oxidizing environments, with better performance in inert atmospheres.

Cold drawing/rolling with precision annealing and laser gauging ensures ±0.05 mm tolerance.

Platinum has higher melting point (1768℃ vs. 1555℃) and better inertness, but palladium is cheaper.
