Disclosed is a flux composition for use in brazing of an aluminum alloy material and includes a flux component [A] containing KAlF.sub.4; and a fluoride [B] containing an element other than Group 1 elements and Group 2 elements and containing no potassium (K). Also disclosed is a brazing sheet which includes an aluminum alloy core; a filler material lying on or over at least one side of the core; and a flux layer lying on or over one side of the filler material and including the flux composition.

Nonwoven fabrics comprising an organopolysiloxane polymer coating that can impart softness to said nonwoven fabric surface. Also disclosed are disposable absorbent articles comprising said nonwoven fabrics.

Provided is a sliding material including a substrate; and a copper alloy layer bonded to the substrate. The copper alloy includes 2.0 to 15.0% by mass of tin. The copper alloy layer includes a sliding body part including a sliding surface, and a gradient region including a bond surface with the substrate. A tin concentration in the gradient region reduces from the sliding body part toward the bond surface. A method for producing the siding material is also provided. The method includes preparing the substrate having a first surface and a second surface opposite to the first surface; melting the copper alloy; casting the molten copper alloy on the first surface of the substrate; and solidifying the copper alloy unidirectionally by cooling the substrate from the second surface by a coolant.

This surface-treated copper foil is characterized in that the amount of adhesion of Si on the copper foil surface is from 3.1 to 300 g/dm.sup.2, and the amount of adhesion of N on the copper foil surface is from 2.5 to 690 g/dm.sup.2. The objective of the present invention is to obtain a copper foil having improved peel strength in providing a copper foil for a flexible printed substrate (FPC), in which a copper foil is laminated to a liquid crystal polymer (LCP) suitable for high-frequency applications.

The present invention provides a steel sheet or part suitable for enamelling. The steel sheet or part is coated with a coating including polymer in which particles of non-oxide ceramic are homogeneously dispersed. A process for producing an enamelled steel sheet or part which has a reduced firing temperature and reduced time compared with conventional firing temperatures and times is also provided. An enamelled steel sheet or part are also provided.

Certain embodiments described herein are directed to composite materials effective for use in deep draw processes. In some examples, the composites can be used to provide vehicle panels such as, for example, vehicle underbody panels. In some configurations, the composite comprises a fiber reinforced polymer core and a skin material disposed on at least some portion of the fiber reinforced polymer core, in which the skin material comprises a basis weight of at least 65 g/m2 and an elongation at break of at least 20%.

A tin-plated copper alloy terminal material in which an Sn-based surface layer is formed on a surface of a base material that is made of copper or a copper alloy, and a CuSn alloy layer and an Ni layer or an Ni alloy layer are sequentially formed between the Sn-based surface layer and the base material from the Sn-based surface layer side: the CuSn alloy layer is a layer that is formed only of an intermetallic compound alloy which is obtained by substituting some of Cu in Cu.sub.6Sn.sub.5 alloy with Ni; and parts of the CuSn alloy layer are exposed from the Sn-based surface layer, thereby forming a plurality of exposed portions; an average thickness of the Sn-based surface layer is from 0.2 m to 0.6 m (inclusive); and an area rate of the exposed portions of the CuSn alloy layer relative to a surface area of is 1% to 40% (inclusive).

The invention relates to a steel sheet skin-pass rolled with a deterministic surface structure, and to a method for producing it.

The present disclosure relates to a high-strength hot-dip galvanized steel sheet having excellent surface quality and electrical resistance spot weldability, and a method for manufacturing the same. A galvanized steel sheet according to an aspect of the present disclosure is a galvanized steel sheet including a base steel sheet and a zinc-based plating layer formed on a surface of the base steel sheet, wherein a ratio (a/b) of a hardness of a surface layer portion (a) to a hardness of an internal portion (b) of the base steel sheet may be less than 0.95.

The present invention relates to a flexible plastic film, and more specifically to a flexible plastic film having excellent flexibility while exhibiting high hardness. According to the present invention, the flexible plastic film exhibits flexibility, bending property, high hardness, scratch resistance and high transparency, and hardly has a risk of damaging the film even in a state of being warped for a long period of time, and thereby can be usefully applied to flexible mobile devices, display devices, front face and display unit of various instrument panels, and the like.
