Our Business

OM Materials (Sarawak) Sdn. Bhd. (“OM Sarawak”) is the Group’s flagship smelter complex in Samalaju, Sarawak. Construction commenced in 2013, and first production was tapped in 2014. The plant consists of 8 main workshops, with two units of 25.5 MVA furnaces in each. Out of the 16 furnaces, 10 are allocated for the production of ferrosilicon, and 6 for the production of manganese alloys.

Commissioned and built to anticipate the current paradigm shift in global ferroalloy production, OM Sarawak is a greenfield smelter located in the Sarawak Corridor of Renewable Energy, Sarawak, Malaysia. Run on renewable hydro-power, it is in the centre of South East Asia and well sited along global trade routes. OM Sarawak will commission a sintering plant in 2019, widening its raw material procurement options by sintering on premises. The facility is expected to produce 250,000 metric tonnes of sinter ore per annum.

Sintering is the process of heating and fusing powdered ore into higher grade, “semi-processed” ores. Smelting is the process of converting raw ores mined from the ground into alloys used in a variety of industrial applications.

The plant has a production capacity of 200,000-210,000 metric tonnes per annum of ferrosilicon (FeSi), and 250,000-300,000 metric tonnes per annum of manganese alloys (see Products).
