On December 2nd, 2010, Pertama Ferroalloys Sdn. Bhd., formerly known as AML Manganese (Malaysia) Sdn. Bhd., was established with the primary objective of producing and distributing manganese alloy products to the global steel industry. It is Malaysia’s first major-scale plant that specializes in producing ferrosilicon and manganese alloys. 

The Pertama smelting plant occupies an area of 180 hectares in the Samalaju Industrial Park in Bintulu, Sarawak as the first manganese alloys and ferrosilicon smelting plant in Malaysia. Construction of the plant started in Q2 of 2010 and the first tapping of the ferrosilicon furnace was successfully carried out in Q2 of 2016. The following tapping of the silicon manganese furnaces were commissioned at regular intervals within the next 6 months until full commercial operations in Q2 of 2017.
