General description:
BALKORE EG is an industrial structural material produced with kiln dried balsa wood planks
glued into blocks and then cross cut sliced into panels of the desired thickness.
The end grain configuration and the honeycomb cell structure of Balsa wood gives to this
material a unique and strong bond to most resins and materials used by the composite
materials industry. The resulting sandwich structures have very high ratios of weight to
mechanical resistance properties.
The EG panels are compatible with all resins commonly used by the composite industry, has
good fire and chemical resistance properties. Depending on the final use, it is available rigid or
flexible. To reduce the resin absortion, the product can be coated with a sealant to reduce
porosity and improve bond strength.

Product Data
HexWeb CR III
Corrosion Resistant Specification Grade Aluminum Honeycomb
!
Description
5052 and 5056 expanded aerospace grade aluminum honeycomb materials are available in a wide selection of
cell sizes and foil gauges. The HexWeb CR III coating has been developed to offer superior protection for aluminum
honeycomb exposed to corrosive environments. The HexWeb CR III system offers a clear protective film that
interacts with the aluminum surface forming a stable, tightly adherent bond. The coating is primarily an organo-
metallic polymer type that differs from the normal conversion-type corrosion protective coatings.
Features
! Aerospace structural grade honeycomb ! Excellent corrosion resistance ! Highest strength and rigidity to weight ratio as a sandwich core ! Maintain corrosion protection at elevated temperatures ! Available in 5052 and 5056 alloys
Applications
Aluminum HexWeb CR III Specification Grade honeycomb materials are predominantly used in sandwich structures
to meet design requirements for highly engineered structural components. As a structural core material, it finds
applications in all types of aerospace vehicles and supporting equipment where sandwich structure offers rigid panels
of minimum weight, aerodynamic smooth surfaces, and high fatigue resistance. The same structural properties are
also used for commercial applications such as tools, snow and water skis, bulkheads, and floors. Other nonstructural
uses are directional air/fluid flow control, RF shielding, and energy absorption.
Type Designation
HexWeb CR III aluminum honeycomb is designated as follows:
Material Cell size Alloy Density
Example: CR-III 3/16 5052 3.1N
Where
CR III designates corrosion resistant honeycomb
3/16 is the cell size in inches
5052 is the alloy of the aluminum
N indicates the cell walls are not perforated.
P indicates cell walls are perforated, and is available on special order
3.1 is the nominal density in pounds per cubic foot
5052 and 5056 are supplied in the H-39 temper
!
HexWeb CR III Product Data

Dimensional Nomenclature
T = Thickness, or cell depth
L = Ribbon direction, or longitudinal direction
W = Transverse direction, or direction perpendicular
to the ribbon
Availability
Lead time varies with the honeycomb type. Please contact a Hexcel Sales Office or Hexcel Customer Service for
price and delivery information.
Specifications
HexWeb CR III expanded aluminum honeycomb materials meet the requirements of Military Specification
MIL-C7438 where applicable.
Standard Dimensions
HexWeb CR III 5052 and 5056 aluminum honeycomb is available in the following standard size:
On special orders Hexcel has the capability of manufacturing HexWeb CR III honeycomb panels in the L dimensions
up to 60 inches maximum, W dimensions up to 150 inches maximum, and T dimensions up to 34 inches maximum,
subject to limitations on some products. Larger sizes may be produced by splicing. Contact the nearest Hexcel Sales
Office for additional information.
Dimensional Tolerances
Tolerances on cut thickness for standard size and smaller sheets are as follows:
Sheet Thickness Standard Tolerances
0.250 in. to 3.999 in. 0.005 in.
4.000 in. and over 0.062 in.
Contact your nearest Hexcel Sales Office with regard to specific dimensional tolerances.
Expanded Sheets
L W Nominal Sq.Ft.
48 in. + 3 in. – 0 in. 96 in. + 4 in. – 0 in. 32.00

Density Tolerance
The nominal densities of the 5052 and 5056 expanded aluminum honeycomb products are shown in Table 1 and II.
The standard density tolerance from the normal density is 10%.
Custom Processing
Aluminum honeycomb can be provided machined or formed ready for bonding. Hexcel has complete facilities for the
manufacture of honeycomb core parts and core assembles. Capabilities include all types of adhesive edge splicing,
machining of simple or compound taper elements with plane or compound curved surfaces, machining of relief areas,
chamfering, drilling, plan form contouring, curvature forming, and similar operations.
Special Products
In addition to the HexWeb CR III hexagonal core honeycomb, Hexcel makes 5052 and 5056 aluminum honeycomb
in several other specialized cell configurations and products; e.g., Flex-Core (Data Sheet 2700), exceptional
formable core material; Corrugated and Reinforced Corrugated Core (Data Sheet 2400), and higher density cores
with superior compressive and crush strengths.
Contact your nearest Hexcel Sales Office for information on these specialized products and on specific processing
requirements.
Mechanical Properties
Mechanical properties of HexWeb CR III 5052 and 5056 alloy honeycomb are shown in Table I and II, respectively.
A major advantage of the HexWeb CR III organo-metallic polymer coating over typical coatings is that HexWeb
CR III is much more resistant to salt spray exposure combined with a prior elevated temperature exposure. Shear
strength retention after 350 F heat aging for up to 500 hours and 30-day salt spray exposure is approximately 88% of
room temperature properties with no salt spray exposure; weight loss is considerably less than the maximum
permissible per MIL-C-7438 for corrosion resistant aluminum honeycomb.
