Marker Bands


Edgetech Industries LLC is a global provider of marker bands for the medical device manufacturing industry. Our marker band’s material: platinum-iridium alloy, gold, or tantalum. Lengths down to 0.25 mm according to clients’ demands via an original process that guarantees high precision and a burr-free finish.

Common applications include radiopaque marking, ring electrodes, cardiac rhythm management devices, stents and angioplasty. It is suitable for radiopaque marker during angioplasty and other minimally-invasive catheter procedure.

Size: OD φ0.2 ~ φ8mm
Wall thickness: 0.015 ~ 0.5mm
Material: tantalum, platinum iridium alloy (Pt90/Ir10)
Standard: ASTM F560

Pure platinum is too soft to cut into small piece as marker band, while platinum iridium (Pt90/Ir10) is suitable for this.

Edgetech Industries has been committed to providing high-precision metal capillary and their derivatives, with an accuracy of “micron”. We specialize in rare metals, special materials, ultra-thin capillary, ultra-thin wall capillary, ultra-high precision capillary, and other fields. The materials of capillary we supply include platinum-iridium (Pt90/Ir10), titanium, tantalum, niobium, niobium zirconium alloy, stainless steel, nickel-base superalloy, etc. Our metal capillaries are used in medical equipment, aerospace, automotive, communication equipment, precision instruments, etc. Representative products are marker bands, puncture needle, heat exchange titanium capillary, oxygen sensor heat pipe, oxygen sensing heat-resistant pipe, fiber optic casing, anti-corrosion tantalum tube, etc.

With our strong research and development capabilities, we can participate in the design and transformation of special machinery in order to meet personalized production needs. Besides research-used products, we can also intensively produce conventional products on a large scale.


Our tantalum marker bands are mostly packed in plastic box & carton, this can protect marker bands during transportation and handling.
