High Ductility And Resistant To Corrosion

Copper Based Alloy Casting

Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion and the best known traditional types are bronze, where tin is a significant addition, and brass which uses zinc instead.

With Copper Based Alloys we are experts in sand casting the following:

LG2and LG4 more commonly known as Leaded Gunmetal Bronze has excellent machinability and great wear resistance with a high resistance to corrosion. This makes it a great all round option often used wear pressure tightness is required such as valve and pump bodies. It also is ideal for plaques and will produce a high quality polished surface

PB1 and PB2 or Phosphor Bronze have a good resistance to cold, corrosion and sea water but are great for use where high mechanical strength and high fatigue strength are needed. Typical applications include load gears and worm drives that have some high speeds as well as high loads. It also performs well under impact and loading so we’re often casting bushes, bearings and impellers in these metals.

AB2 is Aluminium Bronzestrong> which has very high strength, wear and is highly corrosion resistant. A key feature is also its ability to perform through a temperature range of -200c to 200c. High strength cast bushes and cast bearings typically used in aerospace applications are a common casting.

HTB3 or High Tensile Brassstrong> is an option for engineering castings where high wear resistance and high loads are encountered.

LB2 and LB4 are Leaded Brassstrong> alloys which tolerate moderate loading, impact loading and pounding. We regularly use these alloys to cast bearings for high speed pumps, impellers or where high corrosion resistance is required. Or its equally suitable for architectural brackets and also for some artistic applications such as plaques.

DCB or Die Cast Brassstrong> can be die cast as effectively as zinc-based alloys. Most commonly its used to create washers, camshaft components, and decorative products due to the distinctive coloring and potential for surface finishes. Typically, a brass alloy consists of 60 percent copper, 40 percent zinc, and 2 percent aluminum, but there are many variations on this mixture. DCB is capable of yielding products with a durable surface and highly accurate interior specifications and is used in sand casting as well as die casting.

Our Services

Casting Abilities

Pressure Casting
Die casting with accuracy
If you want high volume castings with a high level of dimensional accuracy in aluminium or zinc then our Pressure Die casting plant is the answer.
Shell Moulding
High Dimensional Accuracy
If you require parts with a high dimensional accuracy but perhaps not the volume to consider die casting, then shell moulding provides an ideal solution.
Shell Core Products
Quality castings, in house
Being self-sufficient provides complete control over the quality of your castings so production of cores is always carried out in house.
Sand Casting & Pattern Production
Globally recognised for our skill
Sand casting is one of the oldest and most widely used metal casting skills and ours are recognised by customers across the globe.
Gravity Die Casting & Tooling
Dedicated die casting zone
Our casting design consultants will work with you on your products to design a die that will deliver results time after time and is as cost effective as possible.

Engineering and Finishing

Shot Blasting
For a uniform surface finish
After careful fettling all our castings have the option of being put through our Sisson Lehmann shot blasting machine.
CNC Machining
Completely Machined Castings
To provide a complete one stop engineering solution we can provide completely machined castings using our Haas CNC machining centres.
Powder Coating
In gloss or matt finishes.
Our power coating facility allows us to supply castings painted uniformly, after shot balsting and etching.
Rumbling & Polishing
De-burr and shine!
Castings that may need to be handled are part of assembly or form part of a decorative item can be rumbled to de-burr the surfaces.
Heat Treatment, HiP & Impregnation
Make me stronger!
We perform heat treatment in a highly controlled environment to ensure that the casting retains its original shape without cracking.
Conventional Machining
Castings accurately finished
Simple conventional machining operations are also easily performed by our skilled machinists, to provide an accurate finishing to your castings.
