WebJul 29, 2024 · In general, CTE values for metals fall between those of ceramics (lower values) and polymers (higher values). Common values for metals and alloys are in the range of 10 to 30×10 –6 /K (5.5 to 16.5×10 –6 /°F). The lowest expansion is found in the iron-nickel alloys such as Invar. WebSep 5, 2024 · For all composites, the measured CTE is low or even negative (− 10 ppm K −1) along the z-axis and around 15 ppm K −1 in the x, y -plane. This is geometrically opposite to the properties of the graphite filler (Table 1 ). Aluminum alloys matrices have led to a negative z -CTE. north canton medical foundation https://oakleyautobody.net
