Ferro Alloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese, aluminium, or silicon.

They are used in the production of steels and alloys.

The alloys impart distinctive qualities to alloyed steels and irons or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the leading consumer of ferroalloys.

Nickel is used in many specific and recognizable industrial and consumer products, including stainless steel, alnico magnets, coinage, rechargeable batteries, electric guitar strings, microphone capsules, and special alloys. It is also used for plating and as a green tint in glass.

Nickel is preeminently an alloy metal, and its chief use is in the nickel steels and nickel cast irons, of which there are many varieties. It is also widely used in many other alloys, such as nickel brasses and bronzes, and alloys with copper, chromium, aluminium, lead, cobalt, silver, and gold (Inconel, Incoloy, Monel, Nimonic).

Ferro Niobium is an important iron niobium alloy, with a niobium content of 60-70%. It is the main source for niobium alloying of HSLA steel and covers more than 80% of the world wide niobium production.

The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb2O5. This oxide is mixed with iron oxide and aluminium and is reduced in an aluminothermic reaction to niobium and iron. The ferro niobium can be purified by electron beam melting or used as it is. For alloying with steel the ferro niobium is added to molten steel before casting.

The largest producers of ferro niobium are located in Brazil and Canada.

Ferrosilicon is produced by reduction of silica or sand with coke in presence of iron. Typical sources of iron are scrap iron and millscale. Ferro Silicons with higher silicon content are made in electric arc furnaces. The usual formulations on the market are ferrosilicons with 15%, 45%, 75%, and 90% silicon. The remainder is iron, with about 2% consisting of other elements like aluminium and calcium.

Silicon Metal is a lustrous grey metalloid element. It’s because of it’s lustrous appearance, that metallurgical grade silicon is known as “Silicon Metal.”

It is produced in China, Brazil, Australia, South Africa, Kazakhstan,Thailand, Europe (France, Spain, Germany, Norway, Bosnia and Iceland), as well as in the U.S.A.

Silicon metal is used in the following industries and applications:

As a “hardener” or alloying element in the production of aluminum alloys

In the manufacture of micro processors; solar cells; refractory materials and steel

It is also used as a secondary smelting additive in the manufacture of photonic devices.

Silicon metal is a key ingredient in the production of aluminum as well as many chemical products. Needless to say - it plays an essential role within an exhaustive range of technologies.

​Sectors that are dependent upon it include – the chemical, solar, electronics and energy storage industries. This goes to demonstrate the global economic importance of silicon metal.

Steel Abrasives are steel particles that are used as abrasive or peening media.

They are usually available in two different shapes (shot and grit) that address different industrial applications. Steel shot refers to spherical grains made of molten steel through an atomization ("granulation") process, available in different sizes and hardnesses.

Steel grit characterizes grains with a predominantly angular shape. These grains are obtained by crushing steel shot, therefore they exhibit sharp edges and broken sections. Harder than steel shot, it is also available in different sizes and hardnesses.

Met-Link is predominantly focused on the supply of recycled (environmentally friendly) steel shot, which reduces the amount of waste dumped into our beautiful countryside and provides our customers with a significant saving on monthly consumable costs, without any sacrifice on quality or performance.

Crushed glass grit is a new addition to our range of products, which can be used in many unique applications. The product originates from the recycling of clear glass. Instead of being discarded as waste, this product presents an ever increasing range of uses, which include being used as abrasive media, filtration media, fillers and even for decorative uses.

Our recycled, crushed, glass abrasive media / grit is clear, clean and is well sized to fulfilling various applications. It is an excellent product for cleaning and sand blasting surfaces that require pre-preparation; such as stainless steel, non-ferrous fabricated or cast pieces.

The glass media leaves no residues on surfaces, and is thus non-contaminant and neither does it encourage rust. Additionally, the packaging of the product is designed for user friendly handling, storage and use.

The glass grit is manufactured and supplied in South Africa, providing a significant advantage over imported products such as glass beads, by offering the following benefits;

It is just as effective as glass beads and other imported products.

Proudly South African.

Reliability of supply.

Reduced delivery times.

Reduced costs (international shipping costs cause glass beads to be excessively expensive).

It’s an environmentally friendly, green product. Instead of the glass being discarded and littering the environment, it is re-purposed and utilized in the form of a range of high quality products.

Ferrotitanium is used in steelmaking for deoxidation, grain-size control, and carbon and nitrogen control and stabilization. During steelmaking, titanium is usually introduced as ferrotitanium because of its relatively low melting temperature and high density. Steels with relatively high titanium content include interstitial-free, stainless and high-strength low-alloy steels.

Ferrotitanium is usually produced by induction melting of titanium scrap with iron or steel; however, it also is produced directly from titanium mineral concentrates.

Special Alloys. Met-Link supplies a number of special alloys required for specific customer purposes either sources from pre-selected and varified quality suppliers or via their own production.

Please enquire should you have a requirement for a special alloy.
