Services and Processing
is a leading UK aluminium stockholder and aims to provide a 100% on-time
delivery and quality product both for day-to-day requirements and long term
contracts. We carry out four key roles in the supply chain that help our
customers to perform more cost-effectively:
- we hold stock
- we carry out first stage processing
- we have no minimum quantity
- we maintain traceability
To help achieve these roles Metalweb has
one of the largest ranges of aluminium products in all alloys (including plate, sheet, bar, tube and other extruded
products) carried in stock. This means we can often provide 24 hour delivery
with fully certified material when required.
Large Round Bar
stock a range of large round bar:
- In diameters up to 500mm
- In lengths from 15mm to 4000m in length
- In both metric and imperial dimensions
bar is available from Metalweb in standard aluminium alloys such as
- Aluminium alloy 2011
- Aluminium alloy 2014
- Aluminium alloy 6063
- Aluminium alloy 6082
- Aluminium alloy 7075
also can supply large round bar in specialist aluminium alloys such as
- Aluminium alloy 2024
- Aluminium alloy 2618
- Aluminium alloy 5083
- Aluminium alloy 6061
Aluminium 2011, also known as the “free machining alloy”, machines to an
excellent finish. It often replaces free machining brass without a change of
tooling. The first choice for screw machined parts unless higher strength or
more corrosion resistance is required. Aluminium 2011 contains lead and bismuth
consequently losing popularity to alternatives.
Aluminium 2014 has a tendency to allow the removal of a greater volume of
metal in a single operation for an equivalent standard of finish than 6082.
Durability, however, is lower and it needs a protective coating. Machines better
in solution treated condition than fully heat treated. Used for machined parts
where these characteristics are critical. It is also the most common aerospace
Aluminium 6063 is a low to medium strength alloy suitable for more intricate
sections requiring good corrosion resistance and high surface finish. It is used
in transport and all architectural applications where good anodising
characteristics are essential. It is the most common alloy for shapes from
Aluminium 6082 is the most versatile of all the medium strength aluminium
alloys with good mechanical properties, corrosion resistance, weldability and
machinability. It is the most common commercial rod and bar alloy from stock. Metalweb have
the largest range available.
Aluminium 7075 is a very high strength aircraft alloy displaying good
machinability and hardness. It is not suited for welding or corrosion resistant
Aluminium 2024 is a high strength alloy with excellent machinability widely
used in aircraft. It has limited formability and only fair corrosion resistance
in the heat treated condition. It is not recommended for fusion welding. Typical
applications include high strength parts in aircraft and machinery, including
gears and bolts and for security vans where strength is critical.
Aluminium 2618 is a copper and magnesium containing aluminum alloy. It can be
readily machined. It can be worked both hot and cold and it is typically used to
Aluminium 5083 is stronger than other 5XXX series aluminium alloys such as
5005, 5052, 5251 and 5754. It is used for high strength welded applications with
outstanding joint strength – rail wagons, marine components, bridges, stationary
cryogenic vessels and overhead cranes. It exhibits excellent weldability and
corrosion resistance. Static welded strength is second only to 5754 and 5083 is
superior to 5754 in energy absorption. It is restricted to temperatures below
150ºF = 65.5ºC.
Aluminium Alloy 6061 is the standard structural alloy. It can be easily
welded or brazed with fine finishing characteristics and exhibits good corrosion
resistance. It is similar to 6082 with better formability but more difficult to
extrude and possessing lower strength. It is used for couplings, hardware,
hydraulic pistons, etc.
Services and Processing
In order to minimise inventory, scrap and to maximise throughput rates,
advanced engineering companies demand material to be supplied in exact
quantities, just-in-time and in a form and length that is near to final shape.
normally stocks bar lengths of 3 metres or 4 metres, but a number of items are
held and supplied in longer lengths. In addition Metalweb are
pleased to stock items in special lengths to suit individual customer
operate a range of bar saws which are capable of cutting any size of extruded
bar. Normally bars are cut to a tolerance of ±0.5mm but close tolerance cutting
of bars up to 250mm is possible. Use of CNC controlled, automatic, high speed
circular saws which can cut to ±0.1mm and produce a much superior finish.
also offer a circle/disc and ring cutting service and has specialist cutting
equipment in-house to produce these items.
