High-quality laser gases for reliable manufacturing

Our range of high-quality laser gases includes a variety of premix gases, manufactured to precise specifications, as well as carbon dioxide, helium, oxygen and nitrogen for shielding, cutting and blanketing/purging applications. We also manufacture a range of gases specifically designed for 3D printing applications.

Whether you need a large volume of laser cutting gas, a single oxygen cylinder for gas cutting or variable quantities of any other product from our range, you’ll find our supply and delivery services are the most efficient and reliable in Australia.

Choose the right laser gas for your application

Different laser systems and manufacturing processes require different gas compositions and purity levels. Coregas offers a broad range of high-quality laser gases to suit everything from precision laser cutting to welding and additive manufacturing, including:

  • Laser-grade premixed gases, including the Laspur® range and Lascut-O, developed for specific laser applications.

  • High-purity oxygen for laser cutting applications where faster cutting speeds are required.

  • Nitrogen for producing clean cut edges with minimal oxidation on stainless steel and aluminium.

  • Helium for specialised laser systems and applications requiring stable beam performance.

  • Other industrial and specialty gases for compatible laser, welding and additive manufacturing processes.

If you're selecting a gas for new equipment or changing production requirements, the Coregas team can help identify the most suitable product based on your laser system, material and application.

FAQs



  • Where can I buy laser gas?

    At Coregas, we sell laser gas products directly to customers across Australia and via our network of local depots. If you don’t want to open an account and deal with us directly, you can also order our full range of gases from 3rd party distributors.

  • Which laser gas is best for my application?

    The best laser gas depends on the material being processed and the result you're trying to achieve. Nitrogen is commonly used to produce clean, oxidation-free cuts on stainless steel and aluminium, while oxygen is often selected for cutting carbon steel at higher speeds. Laser-grade premixed gases are also available for specific laser systems. If you're unsure which product is right for your operation, the Coregas team can help.

  • How is laser gas stored?

    For detailed storage instructions, please see the product safety data sheets for the gases you order. In general, all gas cylinders, whether for 3D printing, shielding, nitrogen cutting or any other application, should be kept in a cool, well ventilated storage space, at a fairly constant temperature.

  • How much is laser gas?

    Prices for individual gases and premixes are available on request: please call, email or fax us for full details. We will be happy to prepare a competitive quotation for your consideration and answer any questions you may have about our laser gas range.

  • How long does a cylinder of laser gas last?

    This will depend on the specific application and the equipment being used, as well as on the size of the tank. If you let us know the applicable flow rate and size of cylinders you wish to order, we can let you know roughly how long a single cylinder will last.

  • What gas is used for MIG welding?

    A variety of gases are used in MIG welding. Pure CO2 can be used but a mix of argon, CO2 and oxygen is often preferred. Ultimately, the best choice will depend on the material you are welding: please call for specific advice if required.

  • What gas is used in lasers?

    Compressed helium, CO2, argon, neon, nitrogen, oxygen and xenon are commonly used. Some companies employ a nitrogen generator for laser cutting applications rather than ordering compressed gas but the initial investment and space required may make this an impractical option.

  • What is shielding gas?

    A shielding laser gas performs the same function in laser welding applications as shielding gases in MIG and TIG welding applications. Additionally, it also prevents a plasma cloud from forming in the area above the weld, improving laser penetration and subsequent weld quality.

  • What cylinder sizes are available for laser gases?

    Coregas supplies laser gases in a range of cylinder sizes to suit different production requirements, from occasional workshop use to continuous manufacturing operations. Availability varies depending on the gas type and your location.

  • Where can I buy laser gas?

    Coregas supplies laser gases directly to customers across Australia through our network of local depots. Our products are also available through our distribution network for businesses that prefer to purchase through a third party.

  • Can I arrange ongoing laser gas deliveries?

    Yes. Coregas offers flexible supply options for businesses with regular gas requirements. Scheduled deliveries help maintain a reliable gas supply and reduce the risk of production downtime.
