are primary elements, but are most often used
in alloy or mixed form, and rarely as pure elements,
The differing chemistries lent by the mix of elements in
alloys affect the metal's physical
properties. The mix of properties and differences in
thickness of metal substrates can
affect their coefficient of expansion.
Successful long term bonding
of metal to itself is not too difficult as the different kinds
have relatively close Coefficients of Expansion (COE)s. When
substrates with differing COE's are bonded together,
it is the impact of thermal cycling on the bond that often
tends cause failure over time, even where the initial bond
Thus, bonding metals to other substrates, such as rubber
or glass or plastics, for long term deployment requires careful
and matching of the

and metalloids occupy the majority of space in the periodic
table of elements -- eighty-eightof the one hundred five total elements currently
known. What is interesting is that until the 17th
century only twelve of these eighty-eight metallic elements had
been discovered. The modern manufacturer is faced with considerable
complexity in attempting to adhere metal parts to other substrates
and the adhesive technology available has to be flexible enough
to handle that complexity.
recommended product for bonding metal to metal is BONDiTTM B-536TH
for very high tensile strength
Our recommendation would change if bonding metal to rubber, in
which case we would recommend reading our adhesivesfor rubber page.
Other recommended products if bonding metal to ceramic or glass
B-536TH or B-481TH.
Among the other substrates which metals can be bonded to
using BONDiTTM products
are: UHMW, Delrin, fluoropolymers, copolymers, TPE / TPR,
rubber, polyethylene, polyolefin, polypropylene, polyurethane, silicone,
thermosets, urethane, ceramics, glass, wood, other metals, stone, aggregate
