For more details, pls directly contact us.

Our L605 cobalt chromium alloy tubing is built for the precision and reliability needed in high-performance stents. Conforming to ASTM F90 standards, this tubing is crafted from a cobalt-chromium-tungsten-nickel alloy (L605), with 20% chromium, 15% tungsten, and 10% nickel, delivering tensile strengths of 1000–1450 MPa. It’s the perfect fit for stents that need to navigate tight blood vessels while staying strong and corrosion-resistant.

What makes it special? The alloy’s unique mix gives it a killer combo of flexibility and durability. Chromium forms a protective oxide layer (Cr2O3) that resists corrosion in the body’s harsh environment, while tungsten and nickel boost strength and flexibility, making our tubing ideal for stents that must expand and contract without failing. We use advanced techniques like seamless drawing and micro-scale additive manufacturing to produce ultra-thin, precise tubes tailored to the exacting needs of stent design.

Every tube undergoes rigorous testing to meet FDA and EU EUDAMED standards, ensuring safety for cardiovascular patients. We keep nickel content carefully controlled to minimize allergic risks, making our tubing safe even for sensitive patients. Whether you need micro-tubing for coronary stents or custom sizes for peripheral applications, we deliver solutions that perform flawlessly.

L605 cobalt chromium alloy is a rockstar for stents, and here’s why. Its high tensile strength (1000–1450 MPa) and hardness (550–800 MPa) make it perfect for stents that need to withstand constant blood flow and vessel movement. The alloy’s flexibility is a big win, allowing stents to bend and expand without cracking during deployment.

Corrosion resistance is critical in the body, where blood and saline can degrade lesser materials. The chromium content creates a robust oxide layer that protects against corrosion, ensuring stents last for years without breaking down. Biocompatibility is another strength—L605 is designed to integrate seamlessly with vascular tissues, minimizing inflammation or adverse reactions. We carefully manage nickel content to reduce allergy risks, a key factor for patient safety.

One challenge? L605’s hardness makes it tougher to machine than materials like titanium or stainless steel, especially for micro-scale stent designs. That’s where our expertise comes in. We’ve invested in cutting-edge micro-manufacturing and 3D printing to deliver precise, high-quality tubing without driving up costs. It’s a tough material, but we’ve got it under control.

Applications: Where Our Tubing Makes a Difference

Our L605 cobalt chromium tubing is a game-changer for cardiovascular stents, but its versatility extends to other fields. In medical applications, it’s used for:

• Coronary Stents: Our ultra-thin tubing provides the strength and flexibility needed for stents treating heart disease, ensuring reliable vessel support.

• Peripheral Stents: For larger blood vessels, our tubing offers durability and corrosion resistance for long-term performance.

• Guidewires and Catheters: The alloy’s flexibility and strength make it ideal for navigating complex vascular pathways.

Beyond medical, our L605 tubing excels in:

• Aerospace: Its high-temperature strength and corrosion resistance are perfect for engine components like turbine blades.

• Petrochemical: In harsh chemical environments, our tubing resists corrosion for reliable piping systems.

• Jewelry: Its durability and wear resistance make it a premium choice for high-end accessories.

Industry Analysis: What’s Driving the Market?

The cobalt chromium tubing market is booming, with a projected value of around $500 million in 2025 and a growth rate of 5–12.5% through 2033. We’re at the forefront, meeting the surging demand for high-performance materials. What’s driving this growth?

The cardiovascular device industry is a major force. With heart disease remaining a leading global health issue, the demand for stents is skyrocketing, especially as minimally invasive procedures become more common. Aging populations and rising healthcare spending, particularly in Asia-Pacific, are fueling the need for reliable materials like our L605 tubing.

Technology is a big driver too. Advances in micro-manufacturing and additive manufacturing, like laser melting, allow us to create ultra-precise stent tubing with complex geometries. We’re also seeing a shift toward bioactive coatings that improve stent integration with blood vessels, a trend we’re actively exploring. These innovations are making stents more effective and patient-friendly.

Challenges include high raw material costs for cobalt, chromium, and tungsten, which can squeeze margins. Strict regulations, like FDA approvals and EU’s CE marking, add complexity too. Competition from Titanium Alloy s (lighter) and stainless steel (cheaper) is a factor, but L605’s superior strength, flexibility, and corrosion resistance keep it ahead for stents. We’re leveraging these strengths to stay competitive.

North America and Europe lead the market with their advanced medical industries, but Asia-Pacific is catching up fast, with countries like China and Japan investing heavily in healthcare. We’re expanding our reach to tap into these growing markets.
