Ragnar Welding Supplies, headquartered in Jakarta, Indonesia, is an expert manufacturing and supply company of Cobalt Filler Wire with welding consumables applicable in a variety of industrial fields. Ragnar is known for its precision and reliability and produces cobalt filler wires with a combination of high temperature, wear, and corrosion resistance that deliver superior performance in highly demanding conditions. Our products are found in applications all over aerospace, power generation, petrochemical, and mining industries and fulfil designs that meet international quality controls. Ragnar Welding Supplies is committed to innovation and customer satisfaction in supporting engineers and technicians to improve the performance, longevity, and durability of critical weld components for engineering applications using cobalt welding products.
Typical composition of a cobalt filler wire would be a combination of the principal element Cobalt (balance with), Chromium 25–32%, Tungsten 4–6%, Nickel ≤3%, Carbon 1.5–3%, Silicon ≤1%, and Iron ≤3%, depending on the alloy. There is significant hardness (38–47 HRC), high-temperature strength and wear resistance, and thermal-mechanical stability in combination with heavy thermal and mechanical loadings. Cobalt filler wires exhibit superior resistance to corrosion & oxidation, abrasion, and galling, amongst other qualities, and are suited to industrial and heavy-duty circumstances. The combination of toughness and durability of cobalt filler wires results in a long service life of components exposed to friction, impact, and increased temperatures, and can be manufactured to provide balance of hardness and toughness for aerospace energy and heavy industry.
At Ragnar Welding Supplies, we take pride in being one of Indonesia’s trusted suppliers of high-quality welding consumables. Our expertise lies in Cobalt Filler Wire, engineered for precision, durability, and resistance to corrosion. With a strong commitment to quality and customer satisfaction, we provide welding solutions that support industries across construction, energy, shipbuilding, and manufacturing.
Cobalt filler wire is widely utilized in hardfacing, overlay and repair welding applications where wear, corrosion and heat resistance are essential. Cobalt filler wire is particularly effective for valve seats, turbine blades, pump parts, dies, cutting tools, and bearing surfaces that experience extreme levels of abrasion, impact, and high temperature. Cobalt filler wire finds common application across aerospace, power generation, petrochemical and mining industries because it provides high wear resistance and performance of new or used equipment. Cobalt filler wire is a great choice for your application because of its incredible hardness, toughness, oxidation resistance and galling resistance therefore protecting valuable equipment from the elements and extreme conditions providing service longevity.
