About Gold Marker Bands

American Elements precision manufactures 18K and 24K Gold Marker Bands cut to customer specifications from thin-walled seamless gold tubes in a variety of lengths and diameters; we can also produce marker bands from gold alloys such as gold-platinum and gold-silver. Marker bands are used in the medical industry to provide radiopaque marking for catheter tubes and sensors during angioplasty and other procedures; typical dimensions for marker bands include diameters from 0.2-8.0 mm, wall thicknesses of 0.015-0.5mm, and lengths ranging from 0.2mm up to 25 mm. American Elements can produce most materials in high purity and ultra high purity (up to 99.99999%) forms and follows applicable ASTM testing standards; a range of grades are available including Mil Spec (military grade), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia). Typical and custom packaging is available, as is additional research, technical and safety (MSDS) data.

The number of electrons in each of Gold's shells is 2, 8, 18, 32, 18, 1 and its electron configuration is [Xe]4f¹⁴² 5d¹⁰ 6s¹. The gold atom has a radius of 144 pm and a Van der Waals radius of 217 pm. Gold was first discovered by Early Man prior to 6000 B.C. In its elemental form, gold has a metallic yellow appearance. Gold is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is one of the least reactive chemical elements. Gold is often found as a free element and with silver as a gold-silver alloy. Less commonly, it is found in minerals as gold compounds, usually with tellurium.
