Balls in all materials
Swedens´s largest supplier of Balls!
 

SPEKUMA supply Balls in many different materials. We represent RGP in Italy. See below for different materials:

STEEL BALLS
Spekuma supply Chrome Steel Balls and Carbon Steel Balls.  Chrome Steel have good surface quality, high hardness and is able to operate under heavy load. This type of Balls are mainly used in Bearings and various industrial applications. Carbon Steel has case-hardened surface, can be used in applications that do not require the through hardened Ball. Applications as furniture wheels, locks and toys.

STAINLESS STEEL BALLS
In some applications, the Balls must be resistant to water, steam, oil, gas and chemical liquids. There is hardened , unhardened and acid-resistant Balls of various sizes and depending on the material is resistant to some or all of these liquids. 
Common materials is AISI 420, 440C, 304 and 316.
We have mostly following Stainless Steel Balls in stock:
AISI 420 which is a hardened rust resistant
AISI 316 which is a unhardened Stainless Steel  material

CERAMIC BALLS 
Ceramic Balls are extremely hard and can be used in temperatures up to approx 2000 º C. The material has high abrasion and corrosion resistance. The Balls are non-magnetic and have electrical insulating capacity. Used in Ball Bearings, measuring instrument, valves, pumps, airspacy industry etc. 
Al2O3=Alumina oxide is resistant to most corrosive substances, but should not be used in conjunction with hydrochloric, hydrofluoric acid or other strong alkaline acids. Withstands temperatures -100 till 1600ºC. The colour is white. Purifier types: Ruby which has a red colour and Sapphire which  is transparent.
Si3N4=Silicon Nitride withstands temperatures up to 1200 ºC and has a grey-black colour. 
ZrO2=Zirconium oxide withstand approx 1350 ºC and the colour is white.

TUNGSTEEN CARBIDE BALLS and  STEEL BALLS of other Materials/Alloys
Tungsteen Carbide and Stellite has high wear resistance and hardness, which can withstand hard shocks and impact. Is widely used in marine, mining and petrol industry. We can also supply Aluminium, Brass, Bronze, Copper, Tantalum and Titanium as well as Materials as Monel, Inconel etc. Also the "superalloy" Hastelloy which is nickel-based, can withstand up to 400 ° C and common used in the chemical Industry.

PLASTC BALLS / RUBBER BALLS 
We supply Balls in different plastic materials such as  Nylon= PA, Delrin=POM, Polypropylene=PP, Polyurethane=PUR, Teflon=PTFE  and Torlon Balls and also materials as PEEKPVCPS etc. Rubber Balls in the most common material NBR as well as EPDM, Silicone and Viton.

GLASS BALLS 
Spekuma supply Balls in different kinds of glass materials such as 
soda-limeborosilicate and black glass. Soda-Lime should not be exposed to heat or mechanical shock. They are resistant to some alkaline solutions. Boriosilicate is corrosion resistant , compatible with most acids and has good resistance to thermal shocks. Black-glass Balls are used in technical instruments such as flow meters. 

HOLLOW BALLS
We stock Hollow Balls in Aluminum, these are usually used as decorations. You can also get Hollow Balls in Carbon Steel, Stainless Steel, Brass and Copper as well as Hollow Plastic Balls, which are used as floating elements, they can help reduce evaporation of liquids and emission of unwished steam and also as Roll-On.

OTHER BALLS/MATERIAL 
Spekuma can supply so called Satellites Balls for polishing and tumbling purposes. Also Rubber Balls with Steel core and Steel Balls with partial or drilled-through hole and drilled Balls with a threaded hole.
