Trouble with maintaining
the profile?
Kinks on the inside of the bend? Lost concentricity?
Deformed annular gap?
No such problems with MCP fusible alloys…
Sections, plain or complex - walls, thick or thin.
Any metal ductile enough for bending, and using
conventional bending equipment and tooling.
The MCP low melting-point alloys recommended
for tube and section bending have casting and mechanical
properties specially suited to the optical industry.
|
MCP Quality
|
|
The alloys are produced from high-grade constituents,
following strict specifications. Quality is monitored by an
accredited system conforming to ISO 9002.

|
Workpiece Support Features
|
|
The recommended MCP low melting-point alloys have mechanical
properties that are unusually well suited to the task of support
during bending. It is possible to maintain a constant cross-section
during the process, which may be used successfully on sections
at least as large as 120mm square.
It is also possible to preserve a uniform annular gap while
avoiding wrinkling in bending concentric tubes, for which
purpose the alloy replaces sand, shot or ice as the filler.
The low melting-points ensure that the profile, tube or section
is neither damaged nor distorted during filling and melt-out.

|
Stability & Durability
|
|
With proper attention to usage, the MCP low melting-point
alloys can be re-used continually over periods extending into
years. If the composition is found to have drifted away from
the original specification, it can usually be corrected in-house
by the user. For this purpose, a testing service is available
at the Wellingborough production laboratory. The corrective
amounts of constituents can be supplied as a specially formulated
alloy.

Indications For Use
|
|
MCP 70
|
70-75°C
158-167°F
|
Needs immediate quenching
after the filling. The low melting-point allows use of hot water
for melting out. |
|
MCP 79
|
79°C / 174°F
|
As MCP 70, but lead-
and cadmium-free. |
|
MCP 124
|
124°C / 255°F
|
Suitable for larger
sections. Requires no quenching, but the higher melt-out temperature
means that an oil or other high boiling-point fluid is needed. |
|
Equipment
|
| A range of MCP melting pots
and tanks with volumes up to 15 litres is available
from stock. For your specific purpose, MCP can also design and
supply equipment for melting, dispensing and recovery, able
to cope with low volume, high precision work (e.g. wave guides)
and large section, high volume, precision bending (such as aluminium
structural profiles). |
|
Safety & The Environment
|
| The recommended alloys are not classified as 'dangerous'
for either carriage or supply. They are easy to handle, and
quite safe when the rules for normal handling are observed.
