Oven Capabilities
Our controlled atmosphere ovens allow us to fuse stainless
steel parts without oxidizing the surface. This is achieved
by introducing various blends of gases (such as hydrogen,
nitrogen or argon) into the furnace to achieve the desired
reducing atmosphere.
Our Exothermic ovens allow us to
fuse various metals in an atmosphere which promotes oxidation
of the surface. This type of fusing is typically used to improve
chemical bonding and specific glass wetting requirements.
All of our continuous belt ovens
are capable of fusing in excess of 2000°F. In addition
to fusing, our ovens are also capable of brazing components
which is useful in applications where a ground pin is needed.
High purity and profiling capabilities allow us to meet our
customers' expectations in a cost competitive solution.
Design Capabilities
Our in-house machining, fixturing and CAD capabilities allow
for prototyping and design validation. Our design engineers
have a wide range of equipment available to evaluate quality
and design characteristics. Capabilities include FEA evaluations,
thermal imaging for heat rise determination, a Scanning Electron
Microscope with EDAX software for precision micro-analysis
and chemical composition as well as X-Ray units for sub-surface
analytical evaluations. Standard industry tests such as thermal
shock, voltage, insulation resistance, hermeticity (using
helium mass spectrometers) and burst pressure evaluations
are performed per customer specific requirements. In addition
to our in-house design capabilities, we have an extensive
external Emerson Support Network, which includes Battelle
Institute, Edision Weld Institute, Alfred University, Sarnoff
Research Center and Emerson's Advanced Material Center. Our
design engineers are ready to work with you to develop a robust
product for application.
Smelting
Fusite is one of a select few glass-to-metal sealers able
to formulate custom glasses. Smelting is the process
of taking raw materials to a high temperature to form glass.
For over 50 years, Fusite has pioneered in formulating technical
glasses for glass-to-metal sealing. With thorough knowledge
of glass engineering and chemistry, Fusite continues to exceed
today's stringent material demands for sealing, adhesion and
corrosion resistance. Fusite offers a full range of glasses
covering thermal expansions for most compression and matched
seal applications. From converting the frit to free flowing
granules for dry pressing, Fusite has acquired proven processing
and spray drying equipment.
Combined with extensive technical skills and a fully-capable
research lab, these extensive melting capabilities allow Fusite
to provide custom glass formulations for the customers' most
challenging applications.
Standard glasses produced are:
• Compression Glass – Fusite T
• Matched Glass – Fusite K
• Battery Glass – Fusite 435
Other glasses processed:
• Traditional or custom glasses (9013, etc.)
• Soda-lime (windows) for sight glass
Fusite does not specialize, however, in bora silicate chemicals
or optical grade glass.
Common Pin/Tube Materials
Fusite produces bimetallic wires of various materials and
sizes primarily for applications where high electrical conductivity
is required. Today more and more design engineers are substituting
Fusite’s copper core wire for solid wire because of Fusite’s
proven hermetic metallurgical bond and its compatibility with
many sealing glasses. The copper core permits a conductor
of smaller diameter than solid wire to be used for a given
power requirement. In addition, it maintains excellent mechanical
strength and ductility. Various alloys and copper core ratios
are available with electrical resistivity (@68°F) ranging
from 42-76 ohms-cir. mil./ft.). Diameters as small as .010"
to over .500" are produced on a regular basis.
Our oven and custom glass formulation
capabilities allow for fusing or brazing a variety of different
metals and alloys. Below are some of the more typical pin/tube
materials:
• Copper Cored Stainless Steel Cold Rolled
Steel (1010 or 1008)
• 52 Alloy
• 42 Alloy
• Kovar
• Stainless Steel (300 or 400 Series)
• Molybdenum
Pin/Tube Configurations
Pins or tubes can have a variety of different configurations,
again usually application specific. Common configurations
consist of:
• Straight
• Headed
• Hooked
• Bent
• Flattened and Pierced
• And various machined configurations
Body/Housing Materials
Our oven and custom glass formulation capabilities allow for
fusing or brazing a variety of different metals and alloy,
usually application specific. Below are some of the more typical
body/housing materials used today:
• Cold Rolled Steel (1010 or 1008)
• Kovar
• Stainless Steel (300 or 400 Series)
Plating
Fusite Engineered Products is equipped with both Gold and
Nickel plating operations. Our capabilities include electroless
and electrolytic nickel plating as well as hard and soft gold
plating (soldering and wire bonding quality). Our production
lines have been setup to accommodate the different metal compositions
ranging from cold rolled steel to aluminum (including stainless
steels). In addition to our in-house capabilities, a variety
of other types of plating (including zinc dichromate, zinc
nickel and tin) are available through certified outside suppliers.
To support our plating capabilities,
we are equipped with proven analytical equipment ranging from
X-Ray analysis for plating thickness to salt spray corrosion
resistance evaluation.
