2. とは何ですか 1050 H22 ナンバープレート用アルミシート?

2.1 とは何ですか 1050 アルミニウム合金?

1050 アルミニウム合金 に属します 1xxxシリーズ アルミニウムの, known for its 高純度 (最小 99.5% アルミニウム) 優れた腐食抵抗.

It is a non-heat-treatable alloy that offers outstanding formability and is widely used in applications requiring superior surface finish and moderate strength.

2.2 の化学組成 1050 アルミニウム合金

The high aluminum content gives 1050 its key advantage: clean formability and strong outdoor corrosion resistance.

2.3 What Does H22 Temper Mean?

The temper designation is the most critical factor for license plate manufacturing. "H22" represents a specific thermomechanical history:

• H2 (ひずみ硬化および部分焼きなまし): The metal is cold-rolled to increase its strength (ひずみ硬化) and is then passed through a thermal furnace to partially soften it back to a specific mechanical state.
• 2 (Quarter-Hard): The number '2' signifies the degree of final hardness. It represents a "quarter-hard" 州, positioning the metal perfectly between fully annealed (o-temper, completely soft) and half-hard (H24).

これ "quarter-hard sweet spot" means the metal retains enough yield strength to remain flat and rigid on a vehicle bumper, but is ductile enough to endure the deep, localized stretching required to emboss 3D letters and numbers without tearing or "orange-peeling" at the edges.

2.4 Why License Plates Use 1050 アルミニウム

License plate manufacturers choose 1050 aluminum because it matches the actual working conditions of vehicle plates.

Main advantages include:

• 軽量: aluminum density is about 2.70 g/cm3, much lower than steel.
• No red rust: aluminum forms a natural oxide layer that helps resist corrosion.
• Good embossing formability: raised letters and numbers can be stamped cleanly.
• Surface compatibility: suitable for paint, コーティング, 陽極酸化処理, and reflective film.
• Mass-production efficiency: easy to shear, punch, レベル, and blank.
• リサイクル性: aluminum scrap from blanking and punching has recovery value.

3. 仕様 1050 H22 ナンバープレート用アルミシート

Common license plate sheets often fall around 0.6-1.2 mm 厚さ, depending on country, plate type, embossing depth, and rigidity requirements.

Final thickness should follow the applicable local vehicle registration plate standard.

4. 機械的および物理的特性

Because mechanical properties vary by thickness and production route, buyers should rely on the supplier’s mill test certificate for final values.

5. の製造工程 1050 H22 ナンバープレート用アルミシート

の製造工程は、 1050 H22 aluminum sheet for license plates must control both the aluminum substrate and the final surface condition.

License plate production requires clean surfaces, stable flatness, accurate thickness, and reliable embossing performance.

したがって, each production stage affects the final plate’s appearance, 耐久性, and processing efficiency.

5.1 Raw Material Selection and Alloy Control

Production starts with high-purity aluminum raw material.

以来 1050 アルミニウムが含まれている ≥99.50% aluminum, the mill must control impurity elements such as iron, シリコン, 銅, マグネシウム, マンガン, と亜鉛.

For license plates, chemical consistency matters because different batches must behave similarly during blanking, スタンピング, コーティング, and reflective film lamination.

5.2 溶解と鋳造

The selected aluminum is melted and cast into slabs or coils. During melting, the producer controls temperature, 脱気, 濾過, and impurity levels to reduce inclusions, oxide particles, and internal defects.

5.3 Homogenization and Hot Rolling

キャスト後, homogenization improves the internal structure of the aluminum and reduces segregation.

Hot rolling then reduces the material thickness and prepares it for cold rolling.

Good hot rolling control helps produce a more uniform sheet, which later improves flatness and embossing consistency.

5.4 Cold Rolling to Target Gauge

Cold rolling further reduces the sheet to the required thickness.

For license plate materials, common thickness ranges may be around 0.6-1.2 mm, depending on local standards, plate type, and embossing depth.

Cold rolling improves dimensional accuracy and surface smoothness. It also increases strength through strain hardening, which is necessary before final H22 temper control.

5.5 H22 Temper Control

The H22 temper is achieved through strain hardening and partial annealing.

This step gives the material a quarter-hard condition, balancing strength and formability.

If the temper is too soft, the finished plate may bend too easily. 難しすぎる場合, the embossed areas may crack or show surface damage.

5.6 Tension Leveling and Flatness Correction

Flatness is critical for license plates, especially when the sheet will receive printing, コーティング, or reflective film.

Tension leveling reduces waves, internal stress, and shape defects.

Poor flatness can cause film bubbles, printing misalignment, uneven embossing, or plate warping.

5.7 Surface Cleaning and Pretreatment

塗装前, 絵画, 陽極酸化処理, or reflective film bonding, the aluminum surface must be clean and oil-controlled.

Cleaning removes rolling oil, metal fines, ほこり, 指紋, and oxidation residues.

This stage directly affects coating adhesion and reflective film bonding.

If oil or dust remains on the surface, the plate may suffer from coating peeling, film delamination, 汚れ, or poor weather resistance.

5.8 切断, ブランキング, and Edge Control

The aluminum sheet may be supplied as coil, full sheet, ストリップ, or cut-to-size blanks.

License plate manufacturers often require precise dimensions to match plate standards and stamping dies.

Low-burr edges improve safety and reduce problems during coating, ラミネート加工, およびインストール.

5.9 コーティング, 絵画, or Reflective Film Preparation

Depending on the final license plate system, the sheet may be prepared for different surface processes.

Common surface routes include:

For reflective license plates, 表面の清浄度, 平坦さ, and adhesion performance are especially important because the film must remain bonded under UV exposure, 雨, 熱, cold, and washing chemicals.
