Metal powder – a sustainable material
Powder metallurgy – a green technology
Metal powders are suitable for many different technologies. In powder metallurgy, which means consolidating metal powders into solid components using heat and pressure to fuse the particles together, their advantages become obvious.
Solid metals require forming and milling, processes that require large amounts of energy and create a lot of material waste. Metal powder can produce near net shape components, which means large energy and material savings. With metal powder, it is also possible to achieve shapes that would be difficult or impossible to create using solid metal.

Laser cladding to benefit the environment
Höganäs’ laser cladding application of Rockit® 701 metal powder on the blades of Brazilian sugarcane harvesting machines extends their productivity by more than 14%. Service intervals are prolonged and equipment lifespan is highly increased. This means reduced consumption of raw material and energy and also less waste. In addition, the coated blades provide a more accurate cut, with less damage to the structure of the plants, which allows them to regrow better and more quickly.
Other sustainable solutions enabled by metal powders
Metal powder technology also offers new benefits in many other areas. Here are a few examples:
- Our water treatment solution cleans drinking water from heavy metals and industrial wastewater of contaminants, both with little secondary environmental impact.
- Our soft magnetic composites enable electric motors with outstanding performance and compact design.
- Our surface coating products enable longer lifecycles and less maintenance for machines and tools.
- Our additive manufacturing powders minimize resource use and offer new design opportunities to maximize function.
- New iron-based powders make high temperature brazing of heat exchangers possible.
Metal powders are also used in applications such as welding electrodes, pharmaceuticals, food fortification, metallic paints and medical thermal therapy.
