Processing ServicesProcessed metals save time and

money so many customers have

a need for cutting services.

Understanding this, Aalco is

committed to providing an effective

response and has thus made major

investments in a wide range of

advanced processing equipment at

both local branches and central

facilities. Most branches have on-site

bar sawing, protective PVC coating

of sheet and a guillotine. Central

facilities include plate saws,

polishing of sheet & coil and plasma

profiling as well as coil processing

spanning decoiling, levelling, slitting

and blanking. In addition, Aalco

regularly arranges other services for

customers on a sub-contract basis.

Aalco has developed particular

specialities in four key areas:

Bar, tube and pipe cutting

For bar, capacity is available to

accurately cut anything from a single

16"/406mm diameter billet to high

volume repetition

blanking. For

tubular products

there is an

equally flexible

range of facilities.

This means

reliable deliveries

of cut pieces

across the whole

product range.

Machining

We stock aluminium round bar in three machining alloys:

Alloy 6082 T6 Machines well and, with chip breakers, produces swarfin short tight coils.

Alloy 2011 T3/T6 Often referred to as FMA (Free Machining Alloy),this is produced especially for use on automatic lathes. It offersexceptional machinability at high speeds and forms fine chips whichare easily removed. It is particularly suitable for components withcomplex, detailed or extensive machining and can often replace freemachining brass without tool changes.

Alloy 6262 T9 This may be used in place of Alloy 2011 in applicationsrequiring higher corrosion resistance and better anodising response. It has excellent machinability and surface finishing characteristics.

SPECIAL PRODUCTS

The sizes shown for each product in

this brochure are those most widely

used. Many more options are

available from Aalcos 10,000-item

standard stock range.

In providing customers with a cost-

effective single source for all their

metals requirements, over 50% of

Aalco sales comprise non-standard

products. This covers a significant

range of non-standard products as

well as special items for particular

industries and individual customers

in fact around 40% of the stock at

individual branches falls into this

category together with a

comprehensive processing service

offering items cut to customers

instructions as well as finishing and

coating. The full range of processing

facilities is outlined on pages 2 & 3

of this brochure. In addition, Aalco

regularly arranges sub-contract

processing using a range of

approved suppliers.

Amongst the industries served by

Aalcos speciality product ranges are:

Building Painted Sheet &Extrusions, Patterned Sheet &

Treadplate

Road Transport Sections,Castings, Plate & Shate, Patterned

Sheet & Treadplate

Road Signs Sheet, Blanks,Painted Sheet, Extrusions

Marine Sections, Plate, Sheet,Treadplate, Transition Joints

Aerospace Extrusions includinglarge sections in high strength

alloys, Plate

Process Plant Pipe, Butt WeldFittings & Flanges, Treadplate

Aluminium ExtrusionsAalco are the UKs largest purchaser

of aluminium extrusions with an

annual spend in excess of 25

million representing around 11,000

tonnes. This gives Aalco unrivalled

purchasing power and sourcing

expertise, which is shared with its

customers.

As a major customer of many

leading extrusion mills Aalco has

access to the widest possible range

of alloys, shapes and sizes. In depth

knowledge of each mills particular

specialities means Aalco customers

are assured that their extrusions will

be sourced from the most cost-

effective source.

The stock range includes special

alloys, shapes and sizes for many

industries including building, marine,

road transport, signage, leisure &

sporting goods, engineering and

aerospace.

A particular skill is the sourcing of

bespoke extrusions, designed for

individual customers from single

shapes to full suites. Many

customers have found major

benefits in sourcing from Aalco

rather than direct from the mill.

These benefits include time saving,

reduced costs, flexibility, the

possibility to make regular changes

in scheduled quantities, keeping

abreast of technology changes,

assistance with design and technical

issues, all without sacrificing choice

or quality. Whats more Aalcos

purchasing power means all this can

be achieved at a very competitive

price.

The processing services provided for

aluminium extrusions include:

Cut lengths Single Pieces up to16/406mm diameter through to

High Volume Repetition Cutting

Prefabrication Drilling,Notching, Punching & Bending

Finishing Anodising, Painting/Power Coating, Polishing,

Chromating

Protective Coating or Sleeving

Special Packaging includingKitting

Aluminium can be easily formed byall the main production processesand all alloys are easily formed,welded and joined. It can beextruded into the most complex ofshapes allowing screw fixings, snapfit jointing and attractive designfeatures. It can be drawn to achievethe most exacting of tolerances and to specific levels of hardnessfor the most critical of applications.Then finally it can be hot or coldrolled to provide a multitude ofthicknesses and widths fromcooking foil to heavy plate.Aluminium can be surface rolled togive many attractive, decorativeand functional patterns. Theseinclude popular patterns such as:stucco, checkmate, treadplate andmany more. Aluminium respondswell to a variety of finishingmethods; painting and anodisingare the two most popularly used.Each provides an attractive andhighly durable finish. Theseprocesses can be applied either as apost manufactured operation or asan integrated part of the semisproduction process.

Aluminium is available in a range of alloys giving properties suitablefor an ever-increasing number ofapplications. Major recyclingprogrammes make a significantcontribution to the preservation ofthe environment. Only 5% of theenergy required to smelt primarymetal is used when recycling, which also avoids the problems ofwaste disposal and dumping. Whilst contributing significantly to protecting the environment,aluminium maintains a leadingposition in terms of materialselection by being the most costeffective solution for manyindustrial and consumerapplications.
