We Lead Your Supply Chain
As one of the business sectors within Kim Ann, we offer aerospace specialty metals that are in accordance with aviation standards for requirements of OEM & MRO. Our extensive sourcing network allows us to meet the demanding needs of the aerospace industry. With inventory covering material grades such as copper, nickel, titanium , aluminium, stainless steel and engineering steel grades, the list is non exhaustive with our 20,000 tons centralized warehousing.
Being part of the supply chain, we harness our material inventory to support critical applications, such as landing gears’ components, to non critical applications, such as tooling needs, for mainly MRO sectors.
We pride ourselves in upholding quality by providing the right requirements in accordance to AS 9100, which is part of our accolade.
