Benefits of
Aluminum
Aluminum is a cost effective, low
impact machining material that is
heat treatable and corrosion
resistant. Also aluminum is a
lightweight material that provides
excellent electrical and thermal
conductivity.
Available Coolant Media include:
- Ethylene Glycol
- Coolanol
- PAO
- Flourinerts
- Hydraulics friendly
Limitations
- Operating Environments only up to
300 DegF
- Coefficient of Thermal Expansion (CTE)
Limitations with Board Materials
- Inability to use Untreated Water
as Coolant
Customer
Acceptance:
Aluminum brazing is considered a
special process. Customers look to
established, certified facilities to
perform braze operations.
Technology
Barriers:
Aluminum brazing requires tighter
process parameters than most brazing
processes because of the close
relationship between the melting
point of the braze filler metal and
the base metal. Cleanliness is very
important when brazing aluminum base
metals. Interdependent,
multi-variable control required to
achieve final product specifications
and characteristics makes aluminum
brazing for these markets difficult
to replicate without experienced and
knowledgeable employees.
Capital
Barriers:
Equipment required to perform
aluminum dip and vacuum brazing
process including pre and post
treatments is highly specialized.
Business case must support
investment in infrastructure and
personnel. |
